passage: Year zero Year zero does not exist in the anno Domini system usually used to number years in the Gregorian calendar and in its predecessor, the Julian calendar. In this system, the year 1 BC is followed by AD 1. However, there is a year zero in astronomical year numbering (where it coincides with the Julian year 1 BC) and in ISO 8601:2004 (where it coincides with the Gregorian year 1 BC) as well as in all Buddhist and Hindu calendars.

passage: 504 Year 504 (DIV) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Nicomachus without colleague (or, less frequently, year 1257 "Ab urbe condita"). The denomination 504 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

passage: Time code ambiguity The Year 2000 problem is an example of the pitfalls of time code ambiguity. Very often dates are now recorded with 4 digit years (10/04/1972). Assuming that the use of a 4-digit year field would continue, even in the far future, this would change the time code ambiguity from 100 years to 10 000 years.

passage: Year Zero (political notion) The term Year Zero ( "chhnam saun"), applied to the takeover of Cambodia in April 1975 by the Khmer Rouge, is an analogy to the Year One of the French Revolutionary Calendar. During the French Revolution, after the abolition of the French monarchy (September 20, 1792), the National Convention instituted a new calendar and declared the beginning of the Year I. The Khmer Rouge takeover of Phnom Penh was rapidly followed by a series of drastic revolutionary de-industrialization policies resulting in a death toll that vastly exceeded that of the French Reign of Terror.

passage: Year Zero (political notion) The idea behind Year Zero is that all culture and traditions within a society must be completely destroyed or discarded and a new revolutionary culture must replace it, starting from scratch. All history of a nation or people before Year Zero is deemed largely irrelevant, as it will ideally be purged and replaced from the ground up.

passage: Kurdish calendar The Gregorian calendar has no year 0. The year 1 AD (or 1 CE) was preceded by the year 1 BC (or 1 BCE). Because this can cause confusion when evaluating time periods that include 1 BCE to 1 CE, astronomers sometimes use a different form, employing negative dates and zero: a "-" year or a zero year is always interpreted according to the astronomical reckoning, and a year recorded as BC (or BCE) is always interpreted according to the historians' reckoning. Year 0 would be 1 BC, year -1 would be 2 BC, etc. Then -612 BC is used as the starting year while the Georgian calendar is being used as references; practically, a nomenclature is used that adheres to neither standard.

passage: Anno Mundi Theophilus presents a detailed chronology "from the foundation of the world" to emperor Marcus Aurelius. His chronology begins with the biblical first man Adam through to emperor Marcus Aurelius, in whose reign Theophilus lived. The chronology puts the creation of the world at about 5529 BC: "All the years from the creation of the world amount to a total of 5,698 years." No mention of Jesus of Nazareth is made in his chronology. Seraphim Rose corrected the date to about 5530 BC, to recognise that there is no year 0 in Christian era dating.

passage: Aughts Orthographically, the decade can be written as the "2000s" or the 00s". Some people read "2000s" as "two-thousands", and thus simply refer to the decade as the "Two-Thousands", the "Twenty Hundreds", or the "Twenty-ohs". Some read it as the "00s" (pronounced "Ohs", "Oh Ohs", "Double Ohs" or "Ooze"), while others referred to it as the "Zeros".

passage: Year zero The Anno Domini era was introduced in 525 by Scythian monk Dionysius Exiguus (c. 470–c. 544), who used it to identify the years on his Easter table. He introduced the new era to avoid using the Diocletian era, based on the accession of Roman Emperor Diocletian, as he did not wish to continue the memory of a persecutor of Christians. In the preface to his Easter table, Dionysius stated that the "present year" was "the consulship of Probus Junior [Flavius Anicius Probus Iunior]" which was also 525 years "since the incarnation of our Lord Jesus Christ".[1] How he arrived at that number is unknown.

passage: Anno Domini This calendar era is based on the traditionally reckoned year of the conception or birth of Jesus of Nazareth, with "AD" counting years from the start of this epoch, and "BC" denoting years before the start of the era. There is no year zero in this scheme, so the year AD 1 immediately follows the year 1 BC. This dating system was devised in 525 by Dionysius Exiguus of Scythia Minor, but was not widely used until after 800.

passage: Names for the number 0 in English It is quite common in English to describe decades with a plural of the first year of the decade for example "the nineties" which can be written as "the 90s". There was a debate on what to call the first decade of the 21st century, as "00s" is not usually pronounced as a word. Apart from side stepping the issue and calling the decade the "two-thousands" (2000s) there is no agreed wording, although in Britain and some other countries "noughties" was also used.

passage: Year Zero: The Silent Death of Cambodia Following the programme, some $45 million was raised, unsolicited, in mostly small donations, including almost £4 million raised by schoolchildren in the UK.

passage: Year zero The anno Domini nomenclature was not widely used in Western Europe until the 9th century, and the 1 January to 31 December historical year was not uniform throughout Western Europe until 1752. The first extensive use (hundreds of times) of 'BC' occurred in Fasciculus Temporum by Werner Rolevinck in 1474, alongside years of the world (anno mundi).[5] The terms anno Domini, Dionysian era, Christian era, vulgar era, and common era were used interchangeably between the Renaissance and the 19th century, at least in Latin. But vulgar era was suppressed in English at the beginning of the 20th century after vulgar acquired the meaning of "offensively coarse", replacing its original meaning of "common" or "ordinary". Consequently, historians regard all these eras as equal.

passage: Millennium This is similar to the common demarcation of decades by their most significant digits, e.g., naming the period 1980 to 1989 as the 1980s or "the eighties". Similarly, it would be valid to celebrate the year 2000 as a cultural event in its own right, and name the period 2000 to 2999 would be "the 2000s". In other words, the time period between 1 and 999 (999 years only) would be called the "0s" and the period between 1000 and 1999 would be the "1000s".

passage: Year Zero (album) A planned film adaption of "Year Zero" became a television project in 2007. Reznor met with various writers and pitched the idea to television networks. The 2007–08 Writers Guild of America strike affected the pre-production stage. Nevertheless, Reznor commented in 2008 that the project is "still churning along", and that he had begun working with American film producer Lawrence Bender. In 2010, Reznor started developing the "Year Zero" miniseries with HBO and BBC Worldwide Productions. Reznor and Bender collaborated with "Carnivàle" writer Daniel Knauf to create the science fiction epic. When asked about the miniseries during an "Ask Me Anything" session on Reddit on November 13, 2012, Reznor said it was "currently in a holding state" and explained, "We [Reznor and Sheridan] didn't find the right match with a writer, and really have been avoiding doing what we should have done from the beginning: write it ourselves. [...] This project means a lot to me and will see the light of day in one form or another." In 2017, during an interview promoting new Nine Inch Nails EP "Add Violence", Reznor said that "They got so far as hiring a writer for it, but then it fell to shit because we never had the right writer. I should have just done it [myself]."

passage: Year zero Historians have never included a year zero. This means that between, for example, 1 January 500 BC and 1 January AD 500, there are 999 years: 500 years BC, and 499 years AD preceding 500. In common usage anno Domini 1 is preceded by the year 1 BC, without an intervening year zero.[6] Neither the choice of calendar system (whether Julian or Gregorian) nor the era (Anno Domini or Common Era) determines whether a year zero will be used. If writers do not use the convention of their group (historians or astronomers), they must explicitly state whether they include a year 0 in their count of years, otherwise their historical dates will be misunderstood.[7]

passage: Year zero Dionysius did not use AD years to date any historical event. This began with the English cleric Bede (c. 672–735), who used AD years in his Historia ecclesiastica gentis Anglorum (731), popularizing the era. Bede also used a term similar to the English before Christ once, but that practice did not catch on until very much later. Bede did not sequentially number days of the month, weeks of the year, or months of the year. However, he did number many of the days of the week using a counting origin of one in Ecclesiastical Latin. Previous Christian histories used anno mundi ("in the year of the world") beginning on the first day of creation, or anno Adami ("in the year of Adam") beginning at the creation of Adam five days later (the sixth day of creation according to the Genesis creation narrative), used by Africanus, or anno Abrahami ("in the year of Abraham") beginning 3,412 years after Creation according to the Septuagint, used by Eusebius of Caesarea, all of which assigned "one" to the year beginning at Creation, or the creation of Adam, or the birth of Abraham, respectively. Bede continued this earlier tradition relative to the AD era.

The book offers a comprehensive look at number 0 and its controversing role as one of the great paradoxes of human thought and history since its invention by the ancient Babylonians. Even though zero is a fundamental idea for the modern science, initially the notion of a complete absence got a largely negative, sometimes hostile, treatment by the Western world and Greco-Roman philosophy. "Zero" won 2001 PEN/Martha Albrand Award for First Nonfiction Book.

passage: Signed zero Signed zero is zero with an associated sign. In ordinary arithmetic, the number 0 does not have a sign, so that −0, +0 and 0 are identical. However, in computing, some number representations allow for the existence of two zeros, often denoted by −0 (negative zero) and +0 (positive zero), regarded as equal by the numerical comparison operations but with possible different behaviors in particular operations. This occurs in the "sign and magnitude" and "ones' complement" signed number representations for integers, and in most floating-point number representations. The number 0 is usually encoded as +0, but can be represented by either +0 or −0.

It cannot be prime because it has an infinite number of factors, and cannot be composite because it cannot be expressed as a product of prime numbers (0 must always be one of the factors).

passage: Number The first known documented use of zero dates to AD 628, and appeared in the "Brāhmasphuṭasiddhānta", the main work of the Indian mathematician Brahmagupta. He treated 0 as a number and discussed operations involving it, including division. By this time (the 7th century) the concept had clearly reached Cambodia as Khmer numerals, and documentation shows the idea later spreading to China and the Islamic world.

passage: 0 0 is the integer immediately preceding 1. Zero is an even number because it is divisible by 2 with no remainder. 0 is neither positive nor negative. By most definitions 0 is a natural number, and then the only natural number not to be positive. Zero is a number which quantifies a count or an amount of null size. In most cultures, 0 was identified before the idea of negative things, or quantities less than zero, was accepted.

passage: Year zero In 1627, the German astronomer Johannes Kepler first used an astronomical year which was to become year zero in his Rudolphine Tables. He labeled the year Christi and inserted it between years labeled Ante Christum (BC) and Post Christum (AD) on the mean motion pages of the Sun, Moon, and planets.[9] Then in 1702 the French astronomer Philippe de la Hire used a year he labeled Christum 0 at the end of years labeled ante Christum (BC), immediately before years labeled post Christum (AD) on the mean motion pages in his Tabulæ Astronomicæ, thus adding the designation 0 to Kepler's Christi.[10] Finally, in 1740 the French astronomer Jacques Cassini (Cassini II), who is traditionally credited with the invention of year zero,[11] completed the transition in his Tables astronomiques, simply labeling this year 0, which he placed at the end of years labeled avant Jesus-Christ (BC), immediately before years labeled après Jesus-Christ (AD).[12]

passage: 2000 Popular culture holds the year 2000 as the first year of the 21st century and the 3rd millennium due to a tendency of grouping the years according to decimal values, as if year zero were counted. According to the Gregorian Calendar, these distinctions fall to the year 2001, because the 1st century was retroactively said to start with year AD 1. Since the calendar does not have year zero, its first millennium spanned from years 1 to 1000 inclusively and its second millennium from years 1001 to 2000.

passage: Year zero In astronomy, for the year AD 1 and later it is common to assign the same numbers as the Anno Domini notation, which in turn is numerically equivalent to the Common Era notation. But the discontinuity between 1 AD and 1 BC makes it cumbersome to compare ancient and modern dates. So the year before 1 AD is designated 0, the year before 0 is −1, and so on.

passage: 2000s (decade) In the English-speaking world, a name for the decade was never universally accepted in the same manner as for decades such as the '80s, the '90s, etc. Orthographically, the decade can be written as the "2000s" or the 00s". Common suggestions for referring to this decade: "2000s", "Two-thousands", "Twenty Hundreds", "Twenty-ohs", "00s" (pronounced "Ohs", "Oh Ohs", "Double Ohs" or "Ooze", "Zeros", "Double Zeros"), "the Aughts", "the Noughties", "the Aughties", "the Oughties". Other suggestions from 45 countries suggest the "double nothings", "zilches", "oh-zone", "oh-something". When the "20–" is dropped, the individual years within the decade are usually referred to as starting with an "oh", such as "oh-seven" to refer to the year 2007. During the decade of the 2000s, it was more common to hear years referred to starting with "two-thousand (and)" rather than "twenty-oh". Starting around the middle of the 2010s, it is becoming more common to refer to the individual years of the decade as "twenty-oh-seven" or "twenty-oh-eight" than it had been during the 2000s, although the "two thousand (and)" pattern is still dominant.

passage: Date and time notation in Serbia Years can be written either with four or two digits, and in the latter case, century is usually replaced with an apostrophe (31. 12. ’06.). Leading zero is rarely used, and in those cases which are considered bad practice, only with months (however it is also optional for the days) (6. 05. 2006.). When literal names of the months are used they are not capitalized, and the four-digit format for the year is always used (31. December 2006). Yet another alternative is to use Roman numerals to indicate the month. In this case a dot is omitted (31. XII 2006).

In some instances, his rules differ from the modern standard, specifically the definition of the value of zero divided by zero as zero.

passage: 0 0 (zero) is both a number and the numerical digit used to represent that number in numerals. The number 0 fulfills a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, 0 is used as a placeholder in place value systems. Names for the number 0 in English include zero, nought (UK), naught (US) (), nil, or—in contexts where at least one adjacent digit distinguishes it from the letter "O"—oh or o (). Informal or slang terms for zero include zilch and zip. "Ought" and "aught" (), as well as "cipher", have also been used historically.

passage: Year Zero (video game) The story takes place in the United States in the year 2022, which has been termed "Year 0" by the US government, being the year that America was reborn. The U.S. had suffered several major terrorist attacks, including attacks on Los Angeles and Seattle. In response, the government granted itself emergency powers and seized absolute control on the country. The U.S. government is now a Christian fundamentalist theocracy, maintaining control of the populace through institutions like the Bureau of Morality and the First Evangelical Church of Plano, and locked into near constant war abroad against their aggressors, with the implied ulterior motive to expand their spheres of influence. Americans must get licenses to marry, bear children, etc. Subversive activities can result in these licenses being revoked. Dissenters regularly disappear from their homes in the night, and are detained in federal detainment centers and sanitariums, if not executed.

passage: 0 By the middle of the 2nd millennium BC, the Babylonian mathematics had a sophisticated sexagesimal positional numeral system. The lack of a positional value (or zero) was indicated by a "space" between sexagesimal numerals. By 300 BC, a punctuation symbol (two slanted wedges) was co-opted as a placeholder in the same Babylonian system. In a tablet unearthed at Kish (dating from about 700 BC), the scribe Bêl-bân-aplu wrote his zeros with three hooks, rather than two slanted wedges.

passage: Year 2000 problem Secondly, some programmers had misunderstood the Gregorian calendar rule that determines whether years that are exactly divisible by 100 are not leap years, and assumed that the year 2000 would not be a leap year. In reality, there is a rule in the Gregorian calendar system that states years divisible by 400 are leap years – thus making 2000 a leap year.

passage: 1 BC Year 1 BC was a common year starting on Friday or Saturday (link will display the full calendar) of the Julian calendar (the sources differ, see leap year error for further information) and a leap year starting on Thursday of the Proleptic Julian calendar. It is also a leap year starting on Saturday, in the Proleptic Gregorian calendar. At the time, it was known as the Year of the Consulship of Lentulus and Piso (or, less frequently, year 753 "Ab urbe condita"). The denomination 1 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. The following year is 1 AD in the widely used Julian calendar, which does not have a "year zero".

passage: Astronomical year numbering In his Rudolphine Tables (1627), Johannes Kepler used a prototype of year zero which he labeled "Christi" (Christ's) between years labeled "Ante Christum" (Before Christ) and "Post Christum" (After Christ) on the mean motion tables for the Sun, Moon, Saturn, Jupiter, Mars, Venus and Mercury. In 1702, the French astronomer Philippe de la Hire used a year he labeled at the end of years labeled "ante Christum" (BC), and immediately before years labeled "post Christum" (AD) on the mean motion pages in his "Tabulæ Astronomicæ", thus adding the designation "0" to Kepler's "Christi". Finally, in 1740 the French astronomer Jacques Cassini , who is traditionally credited with the invention of year zero, completed the transition in his "Tables astronomiques", simply labeling this year "0", which he placed at the end of Julian years labeled "avant Jesus-Christ" (before Jesus Christ or BC), and immediately before Julian years labeled "après Jesus-Christ" (after Jesus Christ or AD).

passage: Century In general usage, centuries are aligned with decades by grouping years based on their shared digits. In this model, the 'n' -th century started/will start on the year "(100 x n) - 100" and ends in "(100 x n) - 1". For example, the 20th century is generally regarded as from 1900 to 1999, inclusive. This is sometimes known as the odometer effect. The astronomical year numbering and ISO 8601 systems both contain a year zero, so the first century begins with the year zero, rather than the year one.

passage: Year Zero (album) The "Year Zero" story takes place in the United States in the year 2022; or "Year 0" according to the American government, being the year that America was reborn. The United States has suffered several major terrorist attacks, and in response the government has seized absolute control on the country and reverted to a Christian fundamentalist theocracy. The government maintains control of the populace through institutions such as the Bureau of Morality and the First Evangelical Church of Plano, as well as increased surveillance and the secret drugging of tap water with a mild sedative. In response to the increasing oppression of the government, several corporate, government, and subversive websites were transported back in time to the present by a group of scientists working clandestinely against the authoritarian government. The websites-from-the-future were sent to the year 2007 to warn the American people of the impending dystopian future and to prevent it from ever forming in the first place.

passage: Anno Domini In the AD year numbering system, whether applied to the Julian or Gregorian calendars, AD 1 is preceded by 1 BC. There is no year "0" between them, so a new century begins in a year which has "01" as the final digits (e.g., 1801, 1901, 2001). New millennia likewise are considered to have begun in 1001 and 2001. This is at odds with the common conception that centuries and millennia begin when the trailing digits are zeroes (1800, 1900, 2000, etc.); for example, the worldwide celebration of the new millennium took place on New Year's Eve 1999, when the year number ticked over to 2000.

passage: Millennium The "year 2000" has also been a popular phrase referring to an often utopian future, or a year when stories in such a future were set, adding to its cultural significance. There was also media and public interest in the Y2K bug. People liked to compared their odometer as a reason to celebrate the new millennium which goes from 1999 to 2000. Thus, the populist argument was that the new millennium should begin when the zeroes "rolled over" to 2000, i.e., the day after December 31, 1999. Some people thought that the change of the hundreds digit in the year number, and the zeros rolling over, created a sense that a new century had begun.

passage: Century leap year In the Gregorian calendar, a year ending in "00" that is divisible by 400 is a century leap year, with the intercalation of February 29 yielding 366 days instead of 365. Century years (divisible by 100) that are "not" divisible by 400 are not leap years but common years of 365 days. For example, the years 1600, 2000, and 2400 are century leap years since those numbers are divisible by 400, while 1700, 1800, 1900, 2100, 2200, and 2300 are common years despite being divisible by 4. Leap years divisible by 400 always start on a Saturday; thus the leap day February 29 in those years always falls on a Tuesday (dominical letter BA).

passage: Astronomical year numbering The prefix AD and the suffixes CE, BC or BCE (Common Era, Before Christ or Before Common Era) are dropped. The year 1 BC/BCE is numbered 0, the year 2 BC is numbered −1, and in general the year "n" BC/BCE is numbered "−("n" − 1)" (a negative number equal to 1 − "n"). The numbers of AD/CE years are not changed and are written with either no sign or a positive sign; thus in general "n" AD/CE is simply "n" or +"n". For normal calculation a number zero is often needed, here most notably when calculating the number of years in a period that spans the epoch; the end years need only be subtracted from each other.
