Briefly, from 1894 to 1896, years were numbered using 1392 (the year of the founding of the Choson dynasty) as Year 1.  To convert from Korean to Western years, add 1391.  ('503' equates to '1894'.)

Between 1896 and 1910, Korean era names were used: Chonyang 1-2 (1896-1897), Kwangmu 1-11 (1897-1907), Yunghui 1-4 (1907-1910).

During the period of the Japanese Occupation (1910-1945), Japanese era names were used for most of books published in Korea

1868   明治   Meiji  Emperor Meiji, 1868–1912.
1912  大正  Taishō  Emperor Taishō, 1912–1926.

Korean nationalists outside of Korea, however, commonly numbered years using the Western year 2333 B.C. as year 1.  This convention was maintained in South Korea until 1961.  To convert from a 'Tangun' year, simply subtract 2333.  ('4278' equates to '1945'.).   The Western calendar was adopted in 1961.

When the Propositional Government was established in China in 1919, Korean nationalists outside of Korea also began using the Minguk years (Minguk 1 equates to 1919).  

In North Korea, the Juche calendar dates years from 1912, the year of Kim Il-song's birth (Year 1).  To convert from Juche to Western years, add 1911.  ('89' equates to '2000'.)
