Time in North Korea is given by Pyongyang Time or Standard Time of Democratic People's Republic of Korea, which is 8.5 hours ahead of UTC (UTC+08:30) and has been the standard time zone in North Korea since 15 August 2015. When it is midnight (00:00) UTC, it is 8:30 a.m. (08:30) Pyongyang Time. Like South Korea, North Korea does not currently observe daylight saving time.[1] Time keeping in North Korea is under the State Commission for Science and Technology.


The Korean Empire first adopted a standard time that is similar to Pyongyang Standard Time around the beginning of the 20th century. Some sources claim 1908,[2] others claim 1912[3] and yet another claims that mean local standard time was used prior to 1908 and that UTC+08:30 was used from 1 April 1908 to 31 December 1911 and again from 21 March 1954 to 9 August 1961.[4] Korea was annexed by the Empire of Japan in 1910. In 1912, the colonial government changed the time zone to UTC+09:00 to align with Japan Standard Time.

On 5 August 2015, the North Korean government decided to return to UTC+08:30, effective 15 August 2015, and said the official name would be Pyongyang Time or (PYT).[5][6] The government of North Korea made this decision as a rejection of Japanese imperialism; the time zone change went into effect on the 70th anniversary of the end of the Japanese occupation of Korea.[7]
