In East Asia, reckoning by era names chosen by ruling monarchs ceased in the 20th century except for Japan, where they are still used.
It was rarely used in the Roman calendar and in the early Julian calendar – naming the two consuls that held office in a particular year was dominant.
AD 2017 is thus approximately the same as AUC 2770 (2017 753).
The use of consular dating ended in AD 541 when the emperor Justinian I discontinued appointing consuls.
The last consul nominated was Anicius Faustus Albinus Basilius.
Another system that is less commonly found than might be thought was the use of the regnal year of the Roman emperor.
At first, Augustus indicated the year of his reign by counting how many times he had held the office of consul, and how many times the Roman Senate had granted him Tribunican powers, carefully observing the fiction that his powers came from these offices granted to him, rather than from his own person or the many legions under his control.The instant, date, or year from which time is marked is called the epoch of the era. In antiquity, regnal years were counted from the ascension of a monarch.This makes the Chronology of the ancient Near East very difficult to reconstruct, based on disparate and scattered king lists, such as the Sumerian King List or the Babylonian Canon of Kings.This system of calibrating years fell to disuse in 1381 and was replaced by today's Anno Domini.Throughout the Roman and Byzantine periods, the Decapolis and other Hellenized cities of Syria and Palestine used the Pompeian era, counting dates from the Roman general Pompey's conquest of the region in 63 BC.This list of absolute dates has allowed many of the events of the Neo-Assyrian Period to be dated to a specific year, avoiding the chronological debates that characterize earlier periods of Mesopotamian history.
