AD 1 ( I ) or 1 CE was a common year starting on Saturday or Sunday, [note 1] a common year starting on Saturday by the proleptic Julian calendar, and a common year starting on Monday by the proleptic Gregorian calendar. It is the epoch year for the Anno Domini (AD) Christian calendar era, and the 1st year of the 1st century and 1st millennium of the Christian or Common Era (CE).
In the Roman Empire, AD 1 was known as the "Year of the consulship of Gaius Caesar and Lucius Paullus", [1] and less frequently, as the year AUC 754 (see ab urbe condita ). The denomination "AD 1" for this year has been in consistent use since the mid-medieval period when the Anno Domini (AD) calendar era became the prevalent method in Europe for naming years. It was the beginning of the Christian era/common era. The preceding year is 1 BC; there is no year 0 in this numbering scheme. The Anno Domini dating system was devised in AD 525 by Dionysius Exiguus.
The Julian calendar, a 45 BC reform of the Roman calendar, was the calendar used by Rome in AD 1.
The terms anno Domini (AD) and before Christ (BC) are used when designating years in the Julian and Gregorian calendars. The term anno Domini is Medieval Latin and means "in the year of the Lord" but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "anno Domini nostri Jesu Christi", which translates to "in the year of our Lord Jesus Christ". The form "BC" is specific to English, and equivalent abbreviations are used in other languages: the Latin form, rarely used in English, is ante Christum natum (ACN) or ante Christum (AC).
Ab urbe condita, or anno urbis conditae, abbreviated as AUC or AVC, expresses a date in years since 753 BC, the traditional founding of Rome. It is an expression used in antiquity and by classical historians to refer to a given year in Ancient Rome. In reference to the traditional year of the foundation of Rome, the year 1 BC would be written AUC 753, whereas AD 1 would be AUC 754. The foundation of the Roman Empire in 27 BC would be AUC 727. The current year AD 2024 would be AUC 2777.
The 0s BC were the period between 9 BC and 1 BC, the last nine years of the before Christ era. It is one of two "0-to-9" decade-like timespans that contain nine years, along with the 0s.
Year 525 (DXXV) was a common year starting on Wednesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Probus and Philoxenus. The denomination 525 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. In this year, the monk Dionysius Exiguus proposed a calendar starting with the birth of Jesus, so this was the first time the year was designated AD. However, the system was not used in general until the reign of Charlemagne in the 9th century.
The proleptic Julian calendar is produced by extending the Julian calendar backwards to dates preceding AD 8 when the quadrennial leap year stabilized. The leap years that were actually observed between the implementation of the Julian calendar in 45 BC and AD 8 were erratic.
Year 273 (CCLXXIII) was a common year starting on Wednesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Tacitus and Placidianus. The denomination 273 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 year also saw most lost territories to rebellion returned to the Roman Empire by Emperor Aurelian.
Year 1 BC was a common year starting on Friday or Saturday in the Julian calendar and a leap year starting on Thursday in the proleptic Julian calendar. It was 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. 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 AD 1 in the widely used Julian calendar and the proleptic Gregorian calendar, which both do not have a "year zero".
Year 4 BC was a common year starting on Tuesday or Wednesday of the Julian calendar and a common year starting on Monday of the Proleptic Julian calendar. At the time, it was known as the Year of the Consulship of Sabinus and Rufus. The denomination 4 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.
Year 7 BC was a common year starting on Saturday or Sunday of the Julian calendar and a common year starting on Thursday of the Proleptic Julian calendar. In the Roman world, it was known as the Year of the Consulship of Tiberius and Piso. The denomination 7 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.
Dionysius Exiguus was a 6th-century Eastern Roman monk born in Scythia Minor. He was a member of a community of Scythian monks concentrated in Tomis, the major city of Scythia Minor. Dionysius is best known as the inventor of Anno Domini (AD) dating, which is used to number the years of both the Gregorian calendar and the (Christianised) Julian calendar. Almost all churches adopted his computus for the dates of Easter.
A calendar era is the period of time elapsed since one epoch of a calendar and, if it exists, before the next one. For example, it is the year 2024 as per the Gregorian calendar, which numbers its years in the Western Christian era.
Annianus of Alexandria was a monk and writer who flourished in Alexandria during the pontificate of Theophilus I around the beginning of the 5th century.
The Ethiopian calendar, or Ge'ez calendar is the official state civil calendar of Ethiopia and serves as an unofficial customary cultural calendar in Eritrea, and among Ethiopians and Eritreans in the diaspora. It is also an ecclesiastical calendar for Ethiopian Christians and Eritrean Christians belonging to the Orthodox Tewahedo Churches, Eastern Catholic Churches, and Eastern Protestant Christian P'ent'ay Churches. The Ethiopian calendar is a solar calendar that has much in common with the Coptic calendar of the Coptic Orthodox Church of Alexandria and Coptic Catholic Church, but like the Julian calendar, it adds a leap day every four years without exception, and begins the year on 11 or 12th of September in the Gregorian calendar. A gap of seven to eight years between the Ethiopian and Gregorian calendars results from an alternative calculation in determining the date of the Annunciation.
The Era of the Martyrs, also known as the Diocletian era, is a method of numbering years based on the reign of Roman Emperor Diocletian who instigated the last major persecution against Christians in the Empire. It was used by the Church of Alexandria beginning in the 4th century AD and it has been used by the Coptic Orthodox Church of Alexandria from the 5th century until the present. This era was used to number the year in Easter tables produced by the Church of Alexandria.
A year zero does not exist in the Anno Domini (AD) calendar year system commonly used to number years in the Gregorian calendar ; in this system, the year 1 BC is followed directly by year AD 1. However, there is a year zero in both the astronomical year numbering system, and the ISO 8601:2004 system, the interchange standard for all calendar numbering systems. There is also a year zero in most Buddhist and Hindu calendars.
Dionysius Exiguus's Easter table was constructed in the year 525 by Dionysius Exiguus for the years 532–626. He obtained it from an Easter table attributed to Patriarch Cyril of Alexandria for the years 437–531. The latter was constructed around the year 440 by means of extrapolation from an Alexandrian Easter table constructed around the year 390 by Patriarch Theophilus of Alexandria. The great historical importance of Dionysius' Easter table is twofold:
In the year 616 an anonymous scholar extended Dionysius Exiguus' Easter table to an Easter table covering the years 532 up to and including 721. Dionysius' table was published in 525 and only a century later accepted by the church of Rome, which from the third century up till then had given preference to go on using her own, relatively inadequate, Easter tables. From about the middle of the seventh century all controversy between Alexandria and Rome as to the correct date of Easter ceased, as both churches were now using identical tables.
Laurentius Suslyga or Laurence Suslyga (1570–1640), was a Polish Jesuit historian, chronologist, and an author of Baroque visual poetry. He was the first person to claim that Jesus Christ was born in or before 4 BC, not in AD 1 or in 1 BC, as the Christian era would imply. Suslyga was thus questioning the Anno Domini chronology introduced by Dionysius Exiguus in AD 525. Suslyga presented this theory in his 1605 doctoral thesis entitled Theoremata de anno ortus et mortis Domini, deque universa Jesu Christi in carne oeconomia at the University of Graz. Among other arguments, Suslyga's treatise included the following: Herod's son, Philip the Tetrarch, renamed a city (Bethsaida) after Augustus's biological daughter, Julia. Since she had been exiled from Rome by Augustus in 2 BC, Suslyga assumed that Philip must have renamed the city prior to that date, and Herod must have died prior to Philip's becoming a ruler, which pushes the Massacre of the Innocents at least 3, if not more, years before AD 1. Dionysius Exiguus' chronology did need to be questioned; his chronology did not even match the point of view of the early Christians. The Church Fathers generally believed that Jesus was born either in the 41st or 42nd year of the reign of Augustus, that is in 3 or 2 BC.
The date of the birth of Jesus is not stated in the gospels or in any historical sources and the evidence is too incomplete to allow for consistent dating. However, most biblical scholars and ancient historians believe that his birth date is around 4 to 6 BC. Two main approaches have been used to estimate the year of the birth of Jesus: one based on the accounts in the Gospels of his birth with reference to King Herod's reign, and the other by subtracting his stated age of "about 30 years" when he began preaching.
The 0s began on January 1, AD 1 and ended on December 31, AD 9, covering the first nine years of the Common Era. It is one of two "0-to-9" decade-like timespans that contain nine years, along with the 0s BC.
