Time Zone Converter
What time is 3 PM in New York when you're in Tokyo? Pick a date and time, choose the source and target zones, and see the exact converted time — daylight saving handled automatically.
How it works
The tool uses the browser's built-in Intl API with the IANA time zone database. Your entered wall-clock time is interpreted in the source zone (accounting for that zone's UTC offset on that date), then re-rendered in the target zone — so DST transitions are always correct.
Frequently asked questions
Does it handle daylight saving time?
Yes. Offsets come from the IANA database via the Intl API, so the correct offset for the specific date (DST or standard time) is applied automatically.
What does 'Local (your browser)' mean?
It uses whatever time zone your device is currently set to — handy for converting your own time to someone else's.
Why does the hour difference change through the year?
Because zones switch to daylight saving on different dates (or never). The converter shows the difference valid for the exact date you picked.
