About this tool
Convert time between New York and Seoul with live clocks and the current, daylight-saving-aware time difference.
See what time it is in Seoul when you know the time in New York — this converter shows both cities' clocks live and the exact current time difference between them, adjusted automatically for daylight saving. New York runs on the America/New_York zone (ET) and Seoul on Asia/Seoul (KST); the tool reads your browser's own time-zone data, so the offset is always right even across the days each city changes its clocks. Type any New York time to pin the matching Seoul time, or press swap to convert the other way. Nothing is uploaded.
Open New York to Seoul Time Converter on AltFTool — it loads instantly in your browser.
Read the live clocks at the top for the current time in New York and Seoul.
Type a specific time into the New York field to see the matching Seoul time and date.
Press swap to convert Seoul times to New York instead.
The current local time in New York and Seoul updates every second, with each city's UTC offset and abbreviation shown.
Offsets come from the browser's IANA time-zone database, so the difference is correct on either side of a daylight-saving change — no stale table.
Enter a specific New York time to see the exact Seoul time for today, including the date if the conversion crosses midnight.
It runs entirely in your browser — no account, and no times are sent anywhere.
It can change through the year because one or both cities observe daylight saving, so the converter above shows the current difference live rather than a fixed number. New York uses America/New_York and Seoul uses Asia/Seoul.
Type 9:00 into the New York field above and the converter shows the matching Seoul time for today, daylight saving included. It also shows the Seoul date in case the time crosses midnight.
Yes. It uses your browser's own time-zone data (America/New_York for New York, Asia/Seoul for Seoul), which carries each region's daylight-saving rules, so the result stays correct all year.
Yes — press the swap button and the converter flips to show Seoul → New York, with the same live clocks and time picker.
It relies on the standard IANA time-zone database built into your browser, not an approximation, and makes no network calls, so your times stay on your device.
