Japan uses both the imperial chronology and the Common Era.

1. The imperial chronology refers to the chronology method according to the year or year number of the emperor's accession to the throne.

Each new emperor changes the year name when he ascends the throne, for example, 2008 is the "20th year of Heisei" of Emperor Akihito.

2. The Common Era, that is, the Gregorian era, is a chronological method that originated in Western society. Originally called the Age of Christ, also known as the Western Calendar or Western Calendar, it is a calendar made by the Italian physician and philosopher Aloysius Lilius to reform the Julian calendar. In 1582, it was approved by Gregory XIII, then Pope of Rome.
