AD 1



AD 1 (I), 1 AD or 1 CE is the epoch year for the Anno Domini calendar era. It was a common year starting on Saturday or Sunday, a common year starting on Saturday by the proleptic Julian calendar, and a common year starting on Monday by the proleptic Gregorian calendar. In its time, year 1 was known as the Year of the Consulship of Caesar and Paullus, named after Roman consuls Gaius Caesar and Lucius Aemilius Paullus, and less frequently, as year 754 AUC (ab urbe condita) within the Roman Empire. 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/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.

 * Tiberius, under order of Augustus, quells revolts in Germania (AD 1–5).

 * Sapadbizes, Yuezhi prince and King of Kush (Bactria), dies. Heraios succeeds him as king.

Religion

 * Birth of Jesus, as assigned by Dionysius Exiguus in his anno Domini era according to at least one scholar. However, most scholars think Dionysius placed the birth of Jesus in the previous year, 1 BC. Furthermore, most modern scholars do not consider Dionysius' calculations authoritative, placing the event several years earlier (see Chronology of Jesus).
