Time in Seoul

What time is it in Seoul right now?

Seoul is on UTC+9 all year round, which is 9 hours ahead of UTC. So when it is 12:00 UTC, the local time in Seoul is 21:00. The live clock at the top of this page applies that offset to the current moment and refreshes every second.

What time zone is Seoul in?

Seoul uses the Asia/Seoul time zone, shown as GMT+9. Seoul stays on UTC+9 all year and does not change its clocks for daylight saving time. The "compare to your time zone" section above converts any Seoul time into your own local time instantly.

Does Seoul observe daylight saving time?

No — Seoul does not observe daylight saving time. Its clocks stay on UTC+9 every day of the year, so its offset from UTC never moves. The difference between Seoul and another city therefore changes only when that other city starts or ends its own daylight saving period. If you are scheduling across the seasons, treat Seoul as the fixed end of the pair and check the other city's dates instead.

How do I convert Seoul time to my time zone?

Convert Seoul time by taking its UTC+9 offset and applying the difference to your own: subtract Seoul's offset from UTC to get the UTC time, then add your own offset. For example, 09:00 in Seoul is 00:00 UTC. The converter above does this automatically after detecting your device's time zone, and the World Clock meeting planner lays several cities out on one colour-coded 24-hour grid.
