Converting New York time to Seoul time
Set New York as the reference city, then enter the local date and time of your event. The second row shows the corresponding time and date in Seoul. Use the reference selector to convert in the other direction.
Why the date matters
New York follows Eastern Time. Its UTC offset changes between UTC−5 in standard time and UTC−4 during daylight saving time. London and New York change clocks on different dates, so their time difference is not always five hours.
Seoul follows Korea Standard Time, UTC+9, year-round. It shares the same current time as Tokyo. When planning with North America, check whether the local date is the previous or following day.
Winter and summer comparison
These examples compare the same instant (12:00 UTC) on two dates. They are examples, not a fixed year-round time difference.
