There was no year 0. Before A.D.1 came the year B.C.1. Thus, the first century ran for 100 years from A.D.1 until the end of A.D.100; the first millennium, from A.D.1 until the end of A.D.1000; and so the current millennium will not end until December 31, A.D.2000. Calender System: Year Gregorian.2000 Byzantine.7508 Chinese.4636 Indian.1921 Islamic.1420 Jewish.5760 A 6th century scholar, Dionysius Exiguus (Dennis the Short), established the Gregorian calendar in A.D.532 by fixing A.D. (Anno Domini)1 as the time of Jesus Christ’s birth. In Dionysius’ time, the notion of counting from 0 had not yet been introduced to Europe from the Middle East. Jesus Christ was more likely born in B.C.6, but Dionysius’ system has held firm throughout the years. There are, however, some 40 other calendar systems in use, all of which are in different years that change on different dates. Officially, the new millennium will begin at zero hour, Greenwich Mean Time (GMT), also referred to as Coordinated Universal Time (UTC), on January 1, 2001, according to rules adopted at an international conference held in October 1884. But that same conference also decided that this reckoning “shall not interfere with the use of local or other standard time where desirable.” In other words, everyone east of Greenwich will not postpone their parties past midnight local time, and everyone west won’t celebrate early. The year 2000 is special-even though it isn’t the start of the 21st century-because it is a leap year. Julius Caesar devised the leap year to correct for the fact that the earth circles the sun in 352.24219 days. Because this is not a whole number, the months of the year would slowly fall out of sync with the seasons. A fairly precise correction to the Gregorian calendar debuted in 1582, and stated that a century year will only be a leap year if it is evenly divisible by 400-which is true for Y2K. Image: COMMANDER JOHN BORTNIAK, NOAA Corps DAWN OF A NEW MILLENIUM on January 1, 2001 will shine first in Antarctica and resemble the breaking sunrise above. Frank Morgan, the Meenan Third Century Professor of Mathematics at Williams College, gives the following answer, adapted from his upcoming Math Chat Book, which is based on his Math Chat TV show and column, both available at the Mathematical Association of America’s Web site: The inexorable mathematical logic is that the official calendar millennium does not start until the year 2001. The first 2000 years end with the year 2000, and the next thousand start with 2001, the first year of the third millennium. Imagine a vast army of soldiers, with 1,000 men in each row. In the first row are soldiers 1 to 1,000, in the second, 1,001 to 2,000, and in the third, 2,001 to 3,000. The third row starts with soldier 2,001. Or suppose you work 1,000 hours a year. The first year, you work hours 1 to 1,000, the second year hours 1,001 to 2,000, and the third year begins with your 2,001st hour of work. So we should definitely celebrate the official calendar millennium on January 1, 2001. But there is another millennium to celebrate: the millennium of the 2000s, the years that begin with a 2. This change will affect every check we write, every letter we date. It is exciting to see all the digits roll over for the first time since the year advanced from 999 to 1000, when Ethelred II was king of England; as exciting as seeing the odometer in my Ferrari roll over from 99,999 to 100,000 or seeing the whole Senate roll over to 100 new Senators (which probably never will happen, but then again, I don’t really have a Ferrari either). Of course, this change in date is what causes the Y2K problems with computers, which will interpret ’00 as 1900 instead of 2000. So maybe it’s safer to wait until the official 2001 to celebrate. Another question remains: Where on Earth should the celebration begin? You may have seen on TV on New Year’s Eve the earlier celebration of the new year in other time zones. The most common answer is Greenwich, England, on the prime meridian, the starting place of all time zones. Indeed, a plaque on the Greenwich Old Royal Observatory announces “The Millennium starts here.” But that is not the final word. The year 2001, heralding the third millennium, will arrive earlier in England than in America, but it will arrive still earlier farther east in Moscow, still earlier in Japan (that is why it is called the “Land of the Rising Sun”) and so on until you hit the International Date Line and drop back to the previous day. In fact, Fiji is right up against the 180-degree meridian of longitude. But that is not the final word either. The dateline has long had an eastward bulge beyond the 180-degree line, including the South Pacific island of Tonga, situated in a later time zone. But Kiribati, a wide-spread island nation split by the date line, with a different date in each half, has announced a spectacular relocation of the date line eastward around their boundary. Now Kiribati’s Christmas Island will see the new millennium an hour before Tonga. Personally I hope to go to bed early and find a new millennium waiting for me when I awake.

Why 2023 is called 21st century?
The numbering of years and calendrical reckoning has always been a controversial topic. The civil calendar used in most countries is also known as the Gregorian calendar. The initial epoch (first year) of the Common Era (CE) is 1 CE also known as AD 1.
- The first century comprises the years AD 1 through AD 100.
- The second century began with AD 101 and continued through AD 200.
- By extrapolation, the 20th century comprises the years AD 1901-2000.
- Therefore, the 21st century began on 1 January 2001 and will continue through 31 December 2100.
- Similarly, the 1st millennium comprised the years AD 1-1000.
The 2nd millennium comprised the years AD 1001-2000. The 3rd millennium began with AD 2001 and will continue through AD 3000. Over recorded history, many initial epochs have been used for calendrical reckoning. Frequently, years were counted from the ascension of a ruler.
- For a calendrical epoch to be useful, however, it must be tied to a sequence of recorded historical events.
- The initial year of the Common Era was chosen to be first year to commence after the birth of Christ.
- This is the initial epoch of the Julian and Gregorian calendars.
- This epoch was established by the 6th century scholar Dionysius Exiguus who was compiling a table of dates of Easter.
Dionysius followed a previous precedent, extending an existing table (by Cyrillus) covering the period 228-247. This table was reckoned from the beginning of the reign of Emperor Diocletian. However, Dionysius did not want his Easter table “to perpetuate the memory of an impious persecutor of the Church, but preferred to count and denote the years from the Incarnation of our Lord Jesus Christ.” To accomplish this, he designated the years of his table Anni Domini Nostri Jesu Christi 532-550.
- Thus, Dionysius’ Anno Domini 532 is equivalent to Anno Diocletiani 248, establishing a correspondence between the new Christian Era and an existing system associated with historical records.
- Dionysius did not, however, establish an accurate date for the birth of Christ.
- Scholars generally believe that Christ was born a few years before AD 1, but the records are too sketchy to allow a definitive dating.
How are dates prior to an initial epoch recorded? Today it appears obvious that a year designated 1 would be preceded by year 0, which would be preceded by year -1, etc. But the concept of both 0 and negative numbers did not come into common use in Europe until the 16th century.
Even then, these concepts were initially only of interest to mathematicians. Their application to chronological problems did not occur for two more centuries. Instead, years were counted using a succession of initial epochs. Even as Dionysius’ practice of dating from the Incarnation became common in ecclesiastical writings of the middle ages, traditional dating practices continued for civil purposes.
In the 16th century, Joseph Justus Scaliger tried to resolve the patchwork historical eras by placing everything on a single system. Not being ready to deal with negative year counts, he sought an initial epoch in prior to any historical record. His approach was numerological and utilized three calendrical cycles:
the 28-year solar cycle, the 19-year Golden Number cycle, and the 15-year indiction cycle.
The solar cycle is the period after which week days and calendar dates repeat in the Julian calendar. The Golden Number cycle is the period after which moon phases repeat (approximately) on the same calendar dates. The indictions originally referred to the periodic reassessment for an agricultural or land tax in late third-century Roman Egypt.
- Scaliger could characterize a year by the combination of numbers (S,G,I), where S runs from 1 through 28, G from 1 through 19, and I from 1 through 15.
- A given combination will recur after 7980 (= 28 x 19 x 15) years.
- He called this a Julian cycle because it was based on the Julian calendar.
- Scaliger knew that the year of Christ’s birth (as determined by Dionysius Exiguus) is characterized by the number 9 of the solar cycle, by Golden Number 1, and by number 3 of the indiction cycle, or (9,1,3).
Scaliger chose as this initial epoch the year characterized by (1,1,1) and determined that (9,1,3) was year 4713 of his chronological era. John Herschel later adopted Scaliger’s initial epoch for the Julian Day numbers used by astronomers. We would say that Scaliger’s initial epoch was 4713 BC or -4712.
Does a century start at 0 or 1?
Introduction – When the encyclopedia of human folly comes to be written, a page must be reserved for the minor imbecility of the battle of the centuries-the clamorous dispute as to when a century ends. The present bibliography documents the controversy as it has arisen at the end of the 17th, 18th, and 19th centuries, as well as a few skirmishes in the quarrel that has begun to develop with the approach of the third millennium.
The source of the confusion is easy to discern; ever since learning how to write, we have dated our documents with year designations beginning with the digits 19. Obviously, when we must begin to date them starting with 20, we have embarked on a new century! Haven’t we? The answer is no, we have not; we have merely arrived at the last year of the 20th century.
As historians and others involved in measuring time continue to remind us, there was no year 0. In fact, there has never been a system of recording reigns, dynasties, or eras that did not designate its first year as the year 1. To complete a century, one must complete 100 years; the first century of our era ran from the beginning of A.D.1 to the end of A.D.100; the second century began with the year A.D.101.
While the period 1900-1999 is of course a century, as is any period of 100 years, it is incorrect to label it the 20th century, which began January 1, 1901, and will end on December 31, 2000. Only then will the third millennium of our era begin. Those who are unwilling to accept the clarity of simple arithmetic in this matter and who feel strongly that there is something amiss with the result have developed some impressively convoluted arguments to promote their point of view.
Baron Hobhouse, studying some of these arguments as set forth in letters published in the Times of London during the first few days of January 1900, found “that many of the reasons assigned are irrelevant, many are destructive of the conclusion in support of which they are advanced, and that such as would be relevant and logical have no basis whatever to maintain them in point of fact.” He was one of several observers of the fray at the end of the 19th century who predicted that the foolishness would recur with the advent of the year 2000, as people began to look for ways of demonstrating “that 1999 years make up 20 centuries.” As a writer stated in the January 13, 1900, Scientific American, “It is a venerable error, long-lived and perhaps immortal.” The shortness of human life is also a factor; as a century approaches its end, hardly anyone who experienced the previous conflict is still living, so we are doomed to undergo another round.
- Astronomers have been blamed for some of the confusion by their adoption of a chronology that designates the year 1 B.C.
- As 0 and gives the preceding years negative numbers, e.g., 2 B.C.
- Becomes -1, 3 B.C.
- Becomes -2, etc.
- This system permits them to simplify calculations of recurring astronomical events that cross the starting point of our era, such as series of solar eclipses and the apparitions of periodic comets.
However, this scheme affects only the years preceding A.D.1 and cannot be used as a justification for ending subsequent centuries with the 99th year. Some argue that Dionysius Exiguus made a mistake in his determination of the year of Christ’s birth when he devised our present chronology in the sixth century, and that the discrepancy allows us to celebrate the end of a century a year early.
However, even though the starting point of our era may not correspond to the chronologist’s intention, it is still the point from which we count our centuries-each of which still requires 100 years for completion. Nevertheless, as many of the entries in this list (from p.45 on) will indicate, plans to celebrate the opening of the 21st century and the third millennium at midnight on December 31, 1999, have become so widespread that anyone who tries to call attention to the error is disparaged as a pedant and ignored.
Perhaps the only consolation for those intending to observe the correct date is that hotels, cruise ships, supersonic aircraft, and other facilities may be less crowded at the end of the year 2000. Top of Page
What century is 2000 to 2099?
The 21st Century 2000 – 2099.
What year was 1st century?
The 1st century was the century spanning AD 1 ( I ) through AD 100 ( C ) according to the Julian calendar, It is often written as the 1st century AD or 1st century CE to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period,
- The Roman Empire, Han China and the Parthian Persia were the most powerful and hegemonic states.
- During this century, the Roman Empire (ruled by the Julio-Claudian and Flavian dynasties) continued to be in a period relative stability known as Pax Romana, notwithstanding a financial crisis in 33 and a civil war in 69,
In Europe, Rome expanded into Britain and fought wars in Germania and Dacia, In Africa, Rome was challenged by Tacfarinas, who led his own Musulamii tribe and a loose and changing coalition of other Berber tribes before being defeated in 24. In West Asia, Rome defeated a Jewish rebellion (66–73) and fought a war with Parthia from 58–63, though the latter conflict was inconclusive.
In East Asia, the Chinese Western Han dynasty was overthrown and replaced by the Xin dynasty in 9, which in turn faced its own rebel movements (namely the Red Eyebrows and Lulin ), and was replaced by the Eastern Han Dynasty in 25. The Eastern Han dynasty then faced and quelled a rebellion by the Trưng sisters (40–43).
In 58, the Eastern Han dynasty entered a golden age with the Rule of Ming and Zhang, who were generally regarded as able administrators who cared about the welfare of the people and who promoted officials with integrity. On its northern frontier, the Chinese dynasties waged intermittent war with the Xiongnu before emerging victorious in 91.
The states of Funan and Xianbei were also established in this century. The century saw the emergence of Christianity, In the early 30s, Roman governor Pontius Pilate sentenced Jesus to crucifixion ; his suffering and redemptive death by crucifixion would become central aspects of Christian theology concerning the doctrines of salvation and atonement,
Anti-Jewish riots broke out in Alexandria in 38. In 64, the Great Fire of Rome destroyed two-thirds of the city, precipitating the empire’s first persecution of Christians, who were blamed for the disaster. Later in 70, the siege and subsequent sack of Jerusalem and the Second Temple during the First Jewish–Roman War marked a major turning point in Jewish history.
- The loss of mother-city and temple necessitated a reshaping of Jewish culture to ensure its survival.
- Judaism’s Temple-based sects, including the priesthood and the Sadducees, diminished in importance.
- Second Temple Judaism came to an end, while a new form of Judaism that became known as Rabbinic Judaism developed out of Pharisaic school,
Furthermore, the White Horse Temple, the first Buddhist temple in China, was traditionally constructed in 68, though it is not recorded in contemporary sources before 289. Several natural disasters took place in this century. In 17, an earthquake struck the region of Lydia in the Roman province of Asia in Asia Minor (now part of Turkey ), causing the destruction of at least 12 cities, with Sardis being most affected.
Around 44 to 48, a famine took place in Judea, precipitating assistance by Helena of Adiabene and her son, Izates II, In 62, an earthquake of an estimated magnitude of between 5 and 6 and a maximum intensity of IX or X on the Mercalli scale struck the towns of Pompeii and Herculaneum, severely damaging them.
The towns of Pompeii and Herculaneum both suffered major damage, with damage to some buildings also reported from Naples and Nuceria, In 79, Mount Vesuvius violently spewed forth a deadly cloud of super-heated tephra and gases to a height of 33 km (21 mi), ejecting molten rock, pulverized pumice and hot ash,
Why is it 21st century not 20th?
Why 2012 is in the 21st Century – We live in the 21st Century, that is, the 2000s. Similarly when we say “20th Century,” we are referring to the 1900s. All this because, according to the calendar we use, the 1st Century included the years 1-100 (there was no year zero), and the 2nd Century, the years 101-200.

Why the year 2000 is special?
2000 was designated as the International Year for the Culture of Peace and the World Mathematical Year. Popular culture holds the year 2000 as the first year of the 21st century and the 3rd millennium, because of a tendency to group the years according to decimal values, as if non-existent year zero were counted.
