Korean era name

Template:Short description Template:Infobox Korean name/auto Korean era names were titles adopted in historical Korea for the purpose of year identification and numbering. Era names were used during the period of Silla, Goguryeo, Balhae, Taebong, Goryeo, Joseon, and the Korean Empire. Various Korean regimes officially adopted the era names of Chinese dynasties.

Era names originated in 140 BCE in China, during the reign of the Emperor Wu of Han. Since the middle of the 6th century CE, various Korean regimes started to use era names.

Democratic People's Republic of Korea

Era name	Period of use	Length of use	Remark
Juche	1997–present	Current era	1912 (Kim Il-sung's birth date) is designated as the first year and has been used since 1997.

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, 10 May 2026 Juche 115. But in North Korean publications, the Juche year is usually placed before the corresponding CE year, as in Juche 115 (2026).
