Frequently Asked Questions
What is the time difference between KST and CEST?
During standard time, Central European Summer Time is 7 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.
When does CEST start and end?
CEST begins on the last Sunday in March at 02:00 local CET time, when clocks spring forward one hour from CET (UTC+1) to CEST (UTC+2). It ends on the last Sunday in October at 03:00 local CEST time, when clocks fall back to CET. In 2026, CEST runs from March 29 through October 25, covering approximately seven months of the year across all EU member states that observe this schedule.
Is CEST the same as CET?
CEST and CET are two phases of the same Central European Time zone. CET (Central European Time) is the winter offset at UTC+1, observed from late October through late March. CEST (Central European Summer Time) is the summer offset at UTC+2, active during the EU Daylight Saving Time period — meaning Berlin, Paris, and Rome run one hour ahead of their winter clock for roughly seven months each year.
