History of Korean Standard Time

Korea's time zone has a complex history tied to its colonial past. Before 1908, Korea used its own standard based on 127.5°E longitude (UTC+8:30). During Japanese occupation (1910–1945), Korea was forced onto Japan Standard Time (UTC+9).

After liberation in 1945, South Korea briefly returned to UTC+8:30 but switched back to UTC+9 in 1961 under Park Chung-hee for economic alignment with Japan. North Korea adopted UTC+8:30 (“Pyongyang Time”) in 2015 but reverted to UTC+9 in 2018 during inter-Korean talks.

South Korea used DST during the 1988 Seoul Olympics but discontinued it afterward. Today both Koreas use UTC+9.
