FAQ

What time is it in Seoul when it's noon in UTC?: Use the converter above — enter 12:00 on your date in UTC and you'll get the exact Seoul local time, DST included.
Why does the time difference change during the year?: UTC and Seoul may observe daylight saving on different schedules (or not at all), so the gap between them shifts on clock-change dates.
