Frequently Asked Questions
What is the time difference between KST and AKST?
During standard time, Alaska Standard Time is 18 hours behind Korea Standard Time.
Does South Korea observe Daylight Saving Time?
South Korea does not observe Daylight Saving Time and has not done so since 1988, when DST was discontinued following the Seoul Summer Olympics. KST remains fixed at UTC+9:00 every day of the year, meaning the offset between Seoul and any DST-observing country shifts by one hour twice annually when those countries change their clocks.
Are KST and JST the same?
Yes, Korea Standard Time (KST) and Japan Standard Time (JST) share the identical UTC+9:00 offset, and neither country observes Daylight Saving Time. Seoul and Tokyo run on exactly the same clock year-round, which directly supports the deep semiconductor, automotive, and consumer electronics supply chain integration between the two economies.
Does Alaska observe Daylight Saving Time?
Most of Alaska observes Daylight Saving Time, transitioning from Alaska Standard Time (AKST, UTC-09:00) to Alaska Daylight Time (AKDT, UTC-08:00) on the second Sunday in March. Clocks revert to AKST on the first Sunday in November, following the same DST schedule as the contiguous United States.
Is all of Alaska on Alaska Standard Time?
Almost all of Alaska uses AKST, but the westernmost Aleutian Island communities — those located west of 169° 30′ W longitude — observe Hawaii-Aleutian Time (HST, UTC-10:00) instead. This exception reflects their extreme western geographic position, which places them closer in solar time to Hawaii than to Anchorage.
