Time in South Korea
Time in South Korea is given by Korea Standard Time (KST; Korean: 한국 표준시; Hanja: 韓國標準時; RR: Han-guk pyojunsi) and is 9 hours ahead of UTC (UTC+09:00): i.e., when it is midnight (00:00) UTC, it is 9 am (09:00) Korea Standard Time. South Korea does not observe daylight saving time, but experimented with it during the 1988 Seoul Olympics.[1][2] Korea Standard Time is the same as Japan Standard Time, Indonesian Eastern Standard Time and Yakutsk Time. North Korea was also on Korea Standard Time, but in August 2015 adopted Pyongyang Standard Time, which is 30 minutes behind.[3]
History
The Korean Empire adopted a standard time of 8.5 hours ahead of UTC in 1908. In 1912, the Japanese colonial government changed this to UTC+09:00 to align with Japan Standard Time. In 1954 it was reverted to UTC+08:30 and then in 1961, it was changed to UTC+09:00 again.[4]
North Korea announced that it would revert its time zone to UTC+08:30 on 15 August 2015, which coincides with Liberation Day, and adopt the same standard time as in 1908.[5][6]
