The Gregorian calendar was proclaimed by Pope Gregory XIII and took effect in most Catholic states in 1582, in which October 4, 1582 of the Julian calendar was followed by October 15 in the new calendar, correcting for the accumulated discrepancy between the Julian calendar and the equinox as of that date. When comparing historical dates, it's important to note that the Gregorian calendar, used universally today in Western countries and in international commerce, was adopted at different times by different countries. Britain and her colonies (including what is now the United States), did not switch to the Gregorian calendar until 1752, when Wednesday 2nd September in the Julian calendar dawned as Thursday the 14th in the Gregorian.
The Gregorian calendar is a minor correction to the Julian. In the Julian calendar every fourth year is a leap year in which February has 29, not 28 days, but in the Gregorian, years divisible by 100 are not leap years unless they are also divisible by 400. How prescient was Pope Gregory! Whatever the problems of Y2K, they won't include sloppy programming which assumes every year divisible by 4 is a leap year since 2000, unlike the previous and subsequent years divisible by 100, is a leap year. As in the Julian calendar, days are considered to begin at midnight.
The average length of a year in the Gregorian calendar is 365.2425 days compared to the actual solar tropical year (time from equinox to equinox) of 365.24219878 days, so the calendar accumulates one day of error with respect to the solar year about every 3300 years. As a purely solar calendar, no attempt is made to synchronise the start of months to the phases of the Moon.
While one can't properly speak of “Gregorian dates” prior to the adoption of the calendar in 1582, the calendar can be extrapolated to prior dates. In doing so, this implementation uses the convention that the year prior to year 1 is year 0. This differs from the Julian calendar in which there is no year 0—the year before year 1 in the Julian calendar is year −1. The date December 30th, 0 in the Gregorian calendar corresponds to January 1st, 1 in the Julian calendar.
A slight modification of the Gregorian calendar would make it even more
precise. If you add the additional rule that years evenly divisible
by 4000 are not leap years, you obtain an average solar year
of 365.24225 days per year which, compared to the actual mean year
of 365.24219878, is equivalent to an error of one day over a period
of about 19,500 years; this is comparable to errors due to tidal
braking of the rotation of the Earth.
Astronomers, unlike historians, frequently need to do arithmetic
with dates. For example: a double star goes into eclipse every
1583.6 days and its last mid-eclipse was measured to be on
October 17, 2003 at 21:17 UTC. When is the next? Well, you could
get out your calendar and count days, but it's far easier
to convert all the quantities in question to Julian day numbers
and simply add or subtract. Julian days simply enumerate the days
and fraction which have elapsed since the start of the
Julian era, which is defined as beginning at noon
on Monday, 1st January of year 4713 B.C.E. in the Julian
calendar. This date is defined in terms of a cycle of years,
but has the additional advantage that all known historical astronomical
observations bear positive Julian day numbers, and periods can
be determined and events extrapolated by simple addition and
subtraction. Julian dates are a tad eccentric in starting at
noon, but then so are astronomers (and systems programmers!)—when
you've become accustomed to rising after the “crack of noon” and
doing most of your work when the Sun is down, you appreciate
recording your results in a calendar where the date doesn't change
in the middle of your workday. But even the Julian day convention
bears witness to the eurocentrism of 19th century astronomy—noon
at Greenwich is midnight on the other side of the world. But the Julian
day notation is so deeply embedded in astronomy that it is unlikely
to be displaced at any time in the foreseeable future. It is an ideal
system for storing dates in computer programs, free of cultural bias
and discontinuities at various dates, and can be readily transformed
into other calendar systems, as the source code for this page illustrates.
Use Julian days and fractions (stored in 64 bit or longer floating
point numbers) in your programs, and be ready for Y10K, Y100K,
and Y1MM!
While any event in recorded human history can be written as
a positive Julian day number, when working with contemporary
events all those digits can be cumbersome. A Modified
Julian Day (MJD) is created by subtracting 2400000.5
from a Julian day number, and thus represents the number of
days elapsed since midnight (00:00) Universal Time on
November 17, 1858. Modified Julian Days are widely used to
specify the epoch in tables of orbital elements of
artificial Earth satellites. Since no such objects existed
prior to October 4, 1957, all satellite-related MJDs are
positive.
The Julian calendar was proclaimed by Julius Csar in 46 B.C. and underwent several modifications before reaching its final form in 8 C.E. The Julian calendar differs from the Gregorian only in the determination of leap years, lacking the correction for years divisible by 100 and 400 in the Gregorian calendar. In the Julian calendar, any positive year is a leap year if divisible by 4. (Negative years are leap years if the absolute value divided by 4 yields a remainder of 1.) Days are considered to begin at midnight.
In the Julian calendar the average year has a length of 365.25 days.
compared to the actual solar tropical year
of 365.24219878 days. The calendar thus accumulates one day of
error with respect to the solar year every 128 years.
Being a purely solar calendar, no attempt is made to synchronise the
start of months to the phases of the Moon.
The Hebrew (or Jewish) calendar attempts to simultaneously maintain alignment between the months and the seasons and synchronise months with the Moon—it is thus deemed a “luni-solar calendar”. In addition, there are constraints on which days of the week on which a year can begin and to shift otherwise required extra days to prior years to keep the length of the year within the prescribed bounds. This isn't easy, and the computations required are correspondingly intricate.
Years are classified as common (normal) or embolismic (leap) years which occur in a 19 year cycle in years 3, 6, 8, 11, 14, 17, and 19. In an embolismic (leap) year, an extra month of 29 days, “Veadar” or “Adar II”, is added to the end of the year after the month “Adar”, which is designated “Adar I” in such years. Further, years may be deficient, regular, or complete, having respectively 353, 354, or 355 days in a common year and 383, 384, or 385 days in embolismic years. Days are defined as beginning at sunset, and the calendar begins at sunset the night before Monday, October 7, 3761 B.C.E. in the Julian calendar, or Julian day 347995.5. Days are numbered with Sunday as day 1, through Saturday: day 7.
The average length of a month is 29.530594 days, extremely close
to the mean synodic month (time from new Moon to
next new Moon) of 29.530588 days. Such is the accuracy that
more than 13,800 years elapse before a single day
discrepancy between the calendar's average reckoning of the
start of months and the mean time of the new Moon.
Alignment with the solar year is better than the Julian
calendar, but inferior to the Gregorian. The average length
of a year is 365.2468 days compared to the actual solar tropical
year (time from equinox to equinox) of 365.24219 days, so
the calendar accumulates one day of error with respect to
the solar year every 216 years.
The Islamic calendar is purely lunar and consists of twelve alternating months of 30 and 29 days, with the final 29 day month extended to 30 days during leap years. Leap years follow a 30 year cycle and occur in years 1, 5, 7, 10, 13, 16, 18, 21, 24, 26, and 29. Days are considered to begin at sunset. The calendar begins on Friday, July 16th, 622 C.E. in the Julian calendar, Julian day 1948439.5, the day of Muhammad's flight from Mecca to Medina, with sunset on the preceding day reckoned as the first day of the first month of year 1 A.H.—“Anno Hegiræ”—the Arabic word for “separate” or “go away”. The names for the days are just their numbers: Sunday is the first day and Saturday the seventh; the week is considered to begin on Saturday.
Each cycle of 30 years thus contains 19 normal years of 354 days and 11 leap years of 355, so the average length of a year is therefore ((19 354) + (11 355)) / 30 = 354.365… days, with a mean length of month of 1/12 this figure, or 29.53055… days, which closely approximates the mean synodic month (time from new Moon to next new Moon) of 29.530588 days, with the calendar only slipping one day with respect to the Moon every 2525 years. Since the calendar is fixed to the Moon, not the solar year, the months shift with respect to the seasons, with each month beginning about 11 days earlier in each successive solar year.
The calendar presented here is the most commonly used
civil calendar in the Islamic world; for religious purposes
months are defined to start with the first observation of
the crescent of the new Moon.
The modern Persian calendar was adopted in 1925, supplanting (while retaining the month names of) a traditional calendar dating from the eleventh century. The calendar consists of 12 months, the first six of which are 31 days, the next five 30 days, and the final month 29 days in a normal year and 30 days in a leap year.
Each year begins on the day in which the March equinox occurs at or after solar noon at the reference longitude for Iran Standard Time (52°30' E). Days begin at midnight in the standard time zone. There is no leap year rule; 366 day years do not recur in a regular pattern but instead occur whenever that number of days elapse between equinoxes at the reference meridian. The calendar therefore stays perfectly aligned with the seasons. No attempt is made to synchronise months with the phases of the Moon.
There is some controversy about the reference meridian at which the
equinox is determined in this calendar. Various sources cite
Tehran, Esfahan, and the central meridian of Iran Standard Time as
that where the equinox is determined; in this implementation, the
Iran Standard Time longitude is used, as it appears that this is
the criterion used in Iran today. As this calendar is proleptic for all
years prior to 1925 C.E., historical
considerations regarding the capitals of Persia and Iran do not
seem to apply.
As of 2026, there is no official Hindi dub of It Follows released by a major studio.

Pro Tip: Most legal platforms allow you to turn on Hindi Subtitles (.srt files). While it isn't a voice dub, it allows you to understand the tension without infecting your phone with malware from Filmyzilla.

The story centers on a young woman named Jay who, after a romantic encounter with her boyfriend, discovers she has been passed a deadly, supernatural curse. The "Entity" follows its victim at a slow, walking pace and can take the form of anyone—a stranger or even a loved one. The only way to survive is to pass the curse to someone else through intimacy, but even then, if that person dies, the Entity comes back for you. Why Is It So Popular?

The search for "It Follows in Hindi Filmyzilla new" highlights a growing trend among Indian horror fans looking to experience acclaimed international psychological thrillers in their native language. While It Follows remains a cult classic for its unique premise and haunting atmosphere, navigating the world of "Filmyzilla" and unofficial downloads comes with significant risks and better alternatives. The Plot: What Makes 'It Follows' a Must-Watch?
Released originally in 2014, It Follows reinvented the "slasher" genre. The story follows Jay, a young woman who, after a sexual encounter, find herself stalked by a supernatural entity. This entity can look like anyone—a stranger or a loved one—but it only moves at a walking pace. If it catches you, you die. The only way to get rid of it is to "pass it on" to someone else through intimacy.
For Hindi-speaking audiences, the tension and atmospheric dread of the film translate perfectly, making the demand for a Hindi dubbed version exceptionally high. The 'Filmyzilla' Factor: Why Fans Search There
Sites like Filmyzilla have become popular in India because they provide:
Highly Compressed Files: Small sizes (300MB to 700MB) that are easy to download on mobile data.
Dual Audio Options: Often providing both English and Hindi tracks.
New Links: Constant updates for "new" uploads of older cult hits.
However, using such sites is illegal and dangerous. These platforms often host pirated content, which violates copyright laws. Furthermore, clicking on these "new" links often leads to malicious pop-ups, malware, and potential data theft. Is there an Official 'It Follows' Hindi Dub?
While many unofficial sites claim to have a "Filmyzilla New" Hindi version, it is important to check official streaming platforms first. Often, these third-party Hindi dubs are "fan-made" or "unofficial," which can significantly ruin the viewing experience with poor audio quality and inaccurate translations. Safe Ways to Watch Horror Movies in Hindi
Instead of searching for risky downloads, consider these legal avenues:
Netflix & Amazon Prime Video: Both platforms have massive libraries of international horror with high-quality Hindi dubbing and subtitles.
Google Play Movies / Apple TV: You can often rent or buy cult classics like It Follows for a small fee, ensuring the best video and audio quality.
YouTube Movies: Occasionally, licensed distributors release dubbed versions of older films for free or at a low rental cost. Conclusion
While the urge to find "It Follows in Hindi Filmyzilla new" is understandable for fans wanting a quick thrill, the risks of piracy—legal issues and device security—far outweigh the benefits. To truly enjoy the terrifying "slow-crawl" horror of this masterpiece, it is best to stick to official streaming services where the quality matches the director's original vision. Stay safe, and happy (and legal) haunting!

The film revolves around Jay (Maika Monroe), a young woman who, after a seemingly romantic encounter with her new boyfriend, discovers that she is being pursued by a supernatural entity. This entity takes on the form of different people and is relentless in its pursuit. The entity is a manifestation of a curse that is passed through sexual contact.
Performance
The lead actress, Maika Monroe, delivers a convincing performance as Jay, capturing the fear and vulnerability that comes with being stalked by an unstoppable force. The supporting cast, including Daniel Zolghadri and Lili Sepe, also add to the tension and suspense.
Direction
The film's director, David Robert Mitchell, masterfully crafts a sense of unease and tension, using long takes and clever camera work to create an unsettling atmosphere. The movie's pacing is well-balanced, slowly building up the suspense and horror elements.
Horror Elements
The entity in "It Follows" is a clever and terrifying concept, taking on different forms and being seemingly unstoppable. The film's use of practical effects adds to the realism and scariness of the entity.

The Nightmare That Never Stops: An "It Follows" Review
It Follows isn't your typical jump-scare-filled horror movie. Directed by David Robert Mitchell, it tells the story of 19-year-old Jay, who becomes cursed after a sexual encounter. A supernatural entity—which can look like anyone—begins to relentlessly walk toward her. If it catches her, she dies; the only way to stall it is to pass the curse to someone else through intimacy. Why It’s a Modern Classic:
Constant Dread: The entity moves slowly but never stops, making every person in the background of a scene a potential threat.
Metaphorical Depth: Many viewers and critics interpret the entity as a metaphor for trauma, the inevitability of death, or the anxiety of entering adulthood.
Iconic Soundtrack: The 80s-inspired synth score by Disasterpeace creates a dreamlike, unsettling atmosphere that stays with you long after the credits roll. Where to Watch It Legally in India Filmyzilla Hindi Dubbed Movies - Apps on Google Play

The film is largely about the inevitability of trauma and mortality. "It" follows you regardless of whether you believe in it. Watching this in high quality on a proper screen allows you to appreciate the philosophical weight of the story.
Piracy websites constantly re-upload old content with "New" tags to trick search engines. A recent "Camrip" or "Hindi Dubbed" version of It Follows was likely uploaded to Filmyzilla’s new domain. This pushed the search volume by 400% according to third-party tracker estimates.
While major blockbusters (Marvel, DC, Conjuring Universe) get official Hindi dubs, indie gems like It Follows often remain exclusive to English with subtitles. A huge segment of the Indian audience prefers Hindi audio. Because studios haven't provided an official Hindi version, users flock to piracy sites like Filmyzilla looking for fan-made dubs or re-coded audio tracks.
If you haven't seen it yet, It Follows is not your typical jump-scare horror movie. It thrives on "atmospheric dread."
The Plot: The story follows Jay Height (played by Maika Monroe), a nineteen-year-old woman who, after a sexual encounter with her new boyfriend, is cursed with a supernatural entity.
Here is the terrifying rule: The "It" is a shape-shifting entity that can look like anyone—a stranger, a friend, or a loved one. It walks toward you at a slow, steady pace. It never stops. It never runs. If it touches you, it kills you. The only way to survive is to pass the curse to someone else via sex. But if that person dies, the "It" comes back for you.
Why it scares us: The slow pace of the monster is the genius of the film. You can run, drive, or fly away, but you will eventually have to sleep. You will eventually look away. And "It" will be closer.
You might be wondering: Why are Indian audiences suddenly searching for "It Follows in Hindi" on sites like Filmyzilla?
Introduction: The Buzz around the ‘New’ Horror Classic
In the last few weeks, a specific search term has been exploding across Indian Google Trends: "It Follows in Hindi Filmyzilla New".
For the uninitiated, It Follows is a 2014 American supernatural psychological horror film directed by David Robert Mitchell. Despite being nearly a decade old, the film has found a bizarre, second-wave renaissance in India. Coupled with the keyword "Filmyzilla New"—a notorious piracy portal—this search indicates a massive, pent-up demand for high-quality Hollywood horror dubbed in Hindi.
But why is this particular film trending now? And what makes It Follows a must-watch, even if you are tempted by illegal websites? Let’s break down the anatomy of this viral horror sensation.
The Mayans employed three calendars, all organised as hierarchies of cycles of days of various lengths. The Long Count was the principal calendar for historical purposes, the Haab was used as the civil calendar, while the Tzolkin was the religious calendar. All of the Mayan calendars are based on serial counting of days without means for synchronising the calendar to the Sun or Moon, although the Long Count and Haab calendars contain cycles of 360 and 365 days, respectively, which are roughly comparable to the solar year. Based purely on counting days, the Long Count more closely resembles the Julian Day system and contemporary computer representations of date and time than other calendars devised in antiquity. Also distinctly modern in appearance is that days and cycles count from zero, not one as in most other calendars, which simplifies the computation of dates, and that numbers as opposed to names were used for all of the cycles.
| Cycle | Composed of | Total Days |
Years (approx.) |
|---|---|---|---|
| kin | 1 | ||
| uinal | 20 kin | 20 | |
| tun | 18 uinal | 360 | 0.986 |
| katun | 20 tun | 7200 | 19.7 |
| baktun | 20 katun | 144,000 | 394.3 |
| pictun | 20 baktun | 2,880,000 | 7,885 |
| calabtun | 20 piktun | 57,600,000 | 157,704 |
| kinchiltun | 20 calabtun | 1,152,000,000 | 3,154,071 |
| alautun | 20 kinchiltun | 23,040,000,000 | 63,081,429 |
The Long Count calendar is organised into the hierarchy of cycles shown at the right. Each of the cycles is composed of 20 of the next shorter cycle with the exception of the tun, which consists of 18 uinal of 20 days each. This results in a tun of 360 days, which maintains approximate alignment with the solar year over modest intervals—the calendar comes undone from the Sun 5 days every tun.
The Mayans believed at at the conclusion of each pictun cycle of about 7,885 years the universe is destroyed and re-created. Those with apocalyptic inclinations will be relieved to observe that the present cycle will not end until Columbus Day, October 12, 4772 in the Gregorian calendar. Speaking of apocalyptic events, it's amusing to observe that the longest of the cycles in the Mayan calendar, alautun, about 63 million years, is comparable to the 65 million years since the impact which brought down the curtain on the dinosaurs—an impact which occurred near the Yucatan peninsula where, almost an alautun later, the Mayan civilisation flourished. If the universe is going to be destroyed and the end of the current pictun, there's no point in writing dates using the longer cycles, so we dispense with them here.
Dates in the Long Count calendar are written, by convention, as:
baktun . katun . tun . uinal . kin
and thus resemble present-day Internet IP addresses!
For civil purposes the Mayans used the Haab calendar in which the year was divided into 18 named periods of 20 days each, followed by five Uayeb days not considered part of any period. Dates in this calendar are written as a day number (0 to 19 for regular periods and 0 to 4 for the days of Uayeb) followed by the name of the period. This calendar has no concept of year numbers; it simply repeats at the end of the complete 365 day cycle. Consequently, it is not possible, given a date in the Haab calendar, to determine the Long Count or year in other calendars. The 365 day cycle provides better alignment with the solar year than the 360 day tun of the Long Count but, lacking a leap year mechanism, the Haab calendar shifted one day with respect to the seasons about every four years.
The Mayan religion employed the Tzolkin calendar, composed of 20 named periods of 13 days. Unlike the Haab calendar, in which the day numbers increment until the end of the period, at which time the next period name is used and the day count reset to 0, the names and numbers in the Tzolkin calendar advance in parallel. On each successive day, the day number is incremented by 1, being reset to 0 upon reaching 13, and the next in the cycle of twenty names is affixed to it. Since 13 does not evenly divide 20, there are thus a total of 260 day number and period names before the calendar repeats. As with the Haab calendar, cycles are not counted and one cannot, therefore, convert a Tzolkin date into a unique date in other calendars. The 260 day cycle formed the basis for Mayan religious events and has no relation to the solar year or lunar month.
The Mayans frequently specified dates using both the Haab
and Tzolkin calendars; dates of this form repeat only
every 52 solar years.
A bewildering variety of calendars have been and continue to be used in the Indian subcontinent. In 1957 the Indian government's Calendar Reform Committee adopted the National Calendar of India for civil purposes and, in addition, defined guidelines to standardise computation of the religious calendar, which is based on astronomical observations. The civil calendar is used throughout India today for administrative purposes, but a variety of religious calendars remain in use. We present the civil calendar here.
The National Calendar of India is composed of 12 months. The first month, Caitra, is 30 days in normal and 31 days in leap years. This is followed by five consecutive 31 day months, then six 30 day months. Leap years in the Indian calendar occur in the same years as as in the Gregorian calendar; the two calendars thus have identical accuracy and remain synchronised.
Years in the Indian calendar are counted from the start of
the Saka Era, the equinox of March 22nd of year 79 in the
Gregorian calendar, designated day 1 of month
Caitra of year 1 in the Saka Era. The calendar was
officially adopted on 1 Caitra, 1879 Saka Era, or
March 22nd, 1957 Gregorian. Since year 1 of the Indian
calendar differs from year 1 of the Gregorian, to
determine whether a year in the Indian calendar is a leap
year, add 78 to the year of the Saka era then
apply the Gregorian calendar rule to the sum.
The French Republican calendar was adopted by a decree of La Convention Nationale on Gregorian date October 5, 1793 and went into effect the following November 24th, on which day Fabre d'glantine proposed to the Convention the names for the months. It incarnates the revolutionary spirit of “Out with the old! In with the relentlessly rational!” which later gave rise in 1795 to the metric system of weights and measures which has proven more durable than the Republican calendar.
The calendar consists of 12 months of 30 days each, followed by a five- or six-day holiday period, the jours complmentaires or sans-culottides. Months are grouped into four seasons; the three months of each season end with the same letters and rhyme with one another. The calendar begins on Gregorian date September 22nd, 1792, the September equinox and date of the founding of the First Republic. This day is designated the first day of the month of Vendmiaire in year 1 of the Republic. Subsequent years begin on the day in which the September equinox occurs as reckoned at the Paris meridian. Days begin at true solar midnight. Whether the sans-culottides period contains five or six days depends on the actual date of the equinox. Consequently, there is no leap year rule per se: 366 day years do not recur in a regular pattern but instead follow the dictates of astronomy. The calendar therefore stays perfectly aligned with the seasons. No attempt is made to synchronise months with the phases of the Moon.
The Republican calendar is rare in that it has no concept of a seven day week. Each thirty day month is divided into three dcades of ten days each, the last of which, dcadi, was the day of rest. (The word “dcade” may confuse English speakers; the French noun denoting ten years is “dcennie”.) The names of days in the dcade are derived from their number in the ten day sequence. The five or six days of the sans-culottides do not bear the names of the dcade. Instead, each of these holidays commemorates an aspect of the republican spirit. The last, jour de la Rvolution, occurs only in years of 366 days.
Napolon abolished the Republican calendar in favour of the Gregorian on January 1st, 1806. Thus France, one of the first countries to adopt the Gregorian calendar (in December 1582), became the only country to subsequently abandon and then re-adopt it. During the period of the Paris Commune uprising in 1871 the Republican calendar was again briefly used.
The original decree
which established the Republican calendar contained a
contradiction: it defined the year as starting on the day
of the true autumnal equinox in Paris, but further prescribed
a four year cycle called la Franciade, the fourth
year of which would end with le jour de la Rvolution
and hence contain 366 days. These two specifications are
incompatible, as 366 day years defined by the equinox do
not recur on a regular four year schedule. This problem was
recognised shortly after the calendar was proclaimed, but the
calendar was abandoned five years before the first conflict
would have occurred and the issue was never formally resolved. Here
we assume the equinox rule prevails, as a rigid four year
cycle would be no more accurate than the Julian calendar, which
couldn't possibly be the intent of its enlightened Republican
designers.
The
International Standards Organisation
(ISO) issued
Standard ISO 8601, “Representation of Dates” in 1988,
superseding the earlier ISO 2015. The bulk of the standard
consists of standards for representing dates in the
Gregorian calendar including the highly recommended
“YYYY-MM-DD” form which is unambiguous, free of cultural
bias, can be sorted into order without rearrangement, and is
Y9K compliant. In addition, ISO 8601 formally defines the
“calendar week” often encountered in commercial transactions
in Europe. The first calendar week of a year: week 1, is
that week which contains the first Thursday of the year (or,
equivalently, the week which includes January 4th of the
year; the first day of that week is the previous Monday).
The last week: week 52 or 53 depending on the
date of Monday in the first week, is that which contains
December 28th of the year. The first ISO calendar week of a
given year starts with a Monday which can be as early as
December 29th of the previous year or as late as January
4th of the present; the last calendar week can end as late
as Sunday, January 3rd of the subsequent year.
ISO 8601 dates in year, week, and day form are written
with a “W” preceding the week number, which bears a leading
zero if less than 10, for example February 29th, 2000
is written as 2000-02-29 in year, month, day format and
2000-W09-2 in year, week, day form; since the day number
can never exceed 7, only a single digit is required.
The hyphens may be elided for brevity and the day number
omitted if not required. You will frequently see date of
manufacture codes such as “00W09” stamped on products; this
is an abbreviation of 2000-W09, the ninth week of year 2000.
In solar calendars such as the Gregorian, only days and years have physical significance: days are defined by the rotation of the Earth, and years by its orbit about the Sun. Months, decoupled from the phases of the Moon, are but a memory of forgotten lunar calendars, while weeks of seven days are entirely a social construct—while most calendars in use today adopt a cycle of seven day names or numbers, calendars with name cycles ranging from four to sixty days have been used by other cultures in history.
ISO 8601 permits us to jettison the historical and cultural baggage of weeks and months and express a date simply by the year and day number within that year, ranging from 001 for January 1st through 365 (366 in a leap year) for December 31st. This format makes it easy to do arithmetic with dates within a year, and only slightly more complicated for periods which span year boundaries. You'll see this representation used in project planning and for specifying delivery dates. ISO dates in this form are written as “YYYY-DDD”, for example 2000-060 for February 29th, 2000; leading zeroes are always written in the day number, but the hyphen may be omitted for brevity.
All ISO 8601 date formats have the advantages of being
fixed length (at least until the Y10K crisis rolls around) and, when
stored in a computer, of being sorted in date order
by an alphanumeric sort of their textual representations.
The ISO week and day and day of year calendars are
derivative of the Gregorian calendar and share its accuracy.
Development of the Unix operating system began at Bell Laboratories in 1969 by Dennis Ritchie and Ken Thompson, with the first PDP-11 version becoming operational in February 1971. Unix wisely adopted the convention that all internal dates and times (for example, the time of creation and last modification of files) were kept in Universal Time, and converted to local time based on a per-user time zone specification. This far-sighted choice has made it vastly easier to integrate Unix systems into far-flung networks without a chaos of conflicting time settings.
Many machines on which Unix was initially widely deployed could not support arithmetic on integers longer than 32 bits without costly multiple-precision computation in software. The internal representation of time was therefore chosen to be the number of seconds elapsed since 00:00 Universal time on January 1, 1970 in the Gregorian calendar (Julian day 2440587.5), with time stored as a 32 bit signed integer (long in early C implementations).
The influence of Unix time representation has spread well beyond Unix since most C and C++ libraries on other systems provide Unix-compatible time and date functions. The major drawback of Unix time representation is that, if kept as a 32 bit signed quantity, on January 19, 2038 it will go negative, resulting in chaos in programs unprepared for this. Unix and C implementations wisely (for reasons described below) define the result of the time() function as type time_t, which leaves the door open for remediation (by changing the definition to a 64 bit integer, for example) before the clock ticks the dreaded doomsday second.
C compilers on Unix systems prior to 7th Edition lacked the
32-bit long type. On earlier systems time_t,
the value returned by the time() function, was an array
of two 16-bit ints which, concatenated, represented the
32-bit value. This is the reason why time() accepts a
pointer argument to the result (prior to 7th Edition it returned
a status, not the 32-bit time) and ctime() requires a
pointer to its input argument. Thanks to Eric Allman (author
of sendmail) for
pointing out these historical nuggets.
Spreadsheet calculations frequently need to do arithmetic with date and time quantities—for example, calculating the interest on a loan with a given term. When Microsoft Excel was introduced for the PC Windows platform, it defined dates and times as “serial values”, which express dates and times as the number of days elapsed since midnight on January 1, 1900 with time given as a fraction of a day. Midnight on January 1, 1900 is day 1.0 in this scheme. Time zone is unspecified in Excel dates, with the NOW() function returning whatever the computer's clock is set to—in most cases local time, so when combining data from machines in different time zones you usually need to add or subtract the bias, which can differ over the year due to observance of summer time. Here we assume Excel dates represent Universal (Greenwich Mean) time, since there isn't any other rational choice. But don't assume you can always get away with this.
You'd be entitled to think, therefore, that conversion back and forth between PC Excel serial values and Julian day numbers would simply be a matter of adding or subtracting the Julian day number of December 31, 1899 (since the PC Excel days are numbered from 1). But this is a Microsoft calendar, remember, so one must first look to make sure it doesn't contain one of those bonehead blunders characteristic of Microsoft. As is usually the case, one doesn't have to look very far. If you have a copy of PC Excel, fire it up, format a cell as containing a date, and type 60 into it: out pops “February 29, 1900”. News apparently travels very slowly from Rome to Redmond—ever since Pope Gregory revised the calendar in 1582, years divisible by 100 have not been leap years, and consequently the year 1900 contained no February 29th. Due to this morsel of information having been lost somewhere between the Holy See and the Infernal Seattle monopoly, all Excel day numbers for days subsequent to February 28th, 1900 are one day greater than the actual day count from January 1, 1900. Further, note that any computation of the number of days in a period which begins in January or February 1900 and ends in a subsequent month will be off by one—the day count will be one greater than the actual number of days elapsed.
By the time the 1900 blunder was discovered, Excel users had created millions of spreadsheets containing incorrect day numbers, so Microsoft decided to leave the error in place rather than force users to convert their spreadsheets, and the error remains to this day. Note, however, that only 1900 is affected; while the first release of Excel probably also screwed up all years divisible by 100 and hence implemented a purely Julian calendar, contemporary versions do correctly count days in 2000 (which is a leap year, being divisible by 400), 2100, and subsequent end of century years.
PC Excel day numbers are valid only between 1 (January 1, 1900) and
2958465 (December 31, 9999). Although a serial day counting scheme
has no difficulty coping with arbitrary date ranges or days before
the start of the epoch (given sufficient precision in the representation
of numbers), Excel doesn't do so. Day 0 is deemed the idiotic
January 0, 1900 (at least in Excel 97), and negative days and
those in Y10K and beyond are not handled at all. Further, old
versions of Excel did date arithmetic using 16 bit quantities
and did not support day numbers greater than 65380 (December
31, 2078); I do not know in which release of Excel this
limitation was remedied.
Having saddled every PC Excel user with a defective date numbering scheme wasn't enough for Microsoft—nothing ever is. Next, they proceeded to come out with a Macintosh version of Excel which uses an entirely different day numbering system based on the MacOS native time format which counts days elapsed since January 1, 1904. To further obfuscate matters, on the Macintosh they chose to number days from zero rather than 1, so midnight on January 1, 1904 has serial value 0.0. By starting in 1904, they avoided screwing up 1900 as they did on the PC. So now Excel users who interchange data have to cope with two incompatible schemes for counting days, one of which thinks 1900 was a leap year and the other which doesn't go back that far. To compound the fun, you can now select either date system on either platform, so you can't be certain dates are compatible even when receiving data from another user with same kind of machine you're using. I'm sure this was all done in the interest of the “efficiency” of which Microsoft is so fond. As we all know, it would take a computer almost forever to add or subtract four in order to make everything seamlessly interchangeable.
Macintosh Excel day numbers are valid only between 0
(January 1, 1904) and 2957003 (December 31, 9999). Although
a serial day counting scheme has no difficulty coping with
arbitrary date ranges or days before the start of the epoch
(given sufficient precision in the representation of
numbers), Excel doesn't do so. Negative days and those in
Y10K and beyond are not handled at all. Further, old
versions of Excel did date arithmetic using 16 bit
quantities and did not support day numbers greater than
63918 (December 31, 2078); I do not know in which release of
Excel this limitation was remedied.
