During certain periods of tributary relationship with various Chinese empires, Chinese era names were adopted. For example, in the Annals of Joseon Dynasty, years were described with Chinese era names and Sexagenary Cycle. During the Japanese occupation of Korea, Japan used its own era system for colonial Korea.

The North Korean government and associated organizations use a variation of the Gregorian calendar with a Juche year based on April 15, 1912 CE, the date of birth of Kim Il-sung, as year 1. There is no Juche year 0. The calendar was introduced in 1997. Months are unchanged from those in the standard Gregorian calendar. In many instances, the Juche year is given after the CE year, for example, 27 June 2007 Juche 96. But in North Korean publications, the Juche year is usually placed before the corresponding CE year, as in Juche 96 (2007).
