South Korea
does not currently observe daylight saving time, but experimented with it during the 1988 Summer Olympics in Seoul.[3][4] North Korea
North Korea
used Korea Standard Time until 2015, when it adopted Pyongyang Standard Time (UTC+08:30).[5] History[edit] In 1434, inventor Jang Yeong-sil
Jang Yeong-sil
developed Korea's first automatic water clock, which King Sejong adapted as Korea's standard timekeeper. It is likely that Koreans used water clocks to keep time prior to this invention, but no concrete records of them exist.[6] In 1437, Jang Yeong-sil, with Jeong Cho, created a bowl-shaped sundial called the angbu ilgu (Hangul: 앙부일구), which King Sejong had placed in public so anyone could use it.[7] In 1908, the Korean Empire
Korean Empire
adopted a standard time that was 8.5 hours ahead of UTC (UTC+08:30). In 1912, during the Japanese occupation of Korea, the Governor-General of Korea
Governor-General of Korea
changed standard time to UTC+09:00 to align with Japan Standard Time. However, in 1954, the South Korean government under President Syngman Rhee
Syngman Rhee
reverted the standard time to UTC+08:30. Then in 1961, under the military government of President Park Chung-hee, the standard time was changed back to UTC+09:00 once again.[8] In order to accommodate American television viewers, South Korea observed daylight saving time when Seoul
Seoul
hosted the 1988 Summer Olympics. The one-hour time change meant that many daytime events could be broadcast live from South Korea
South Korea
when it was prime time on the U.S. east coast.[3] On August 15, 2015, North Korea
North Korea
reverted its standard time zone to UTC+08:30 to coincide with the National Liberation Day of Korea
National Liberation Day of Korea
from Japan. The North Korean government said it decided to revert to the standard time Korea used before the Japanese occupation began in 1910 in order to break away from the "wicked Japanese imperialists." The time zone is known as Pyongyang Standard Time.[9][5] IANA time zone database[edit] The IANA time zone database
