Time Zone Converter
Convert a date and time between major world time zones with proper daylight-saving handling. Uses the browser's timezone database.

Read the converted time with its UTC offset.
How it works
The browser's ICU timezone database resolves each zone's rules, including daylight-saving transitions. The tool converts your wall-clock time to a single instant and reformats it in the target zone - offsets update automatically across DST boundaries.
Frequently asked questions
Does it handle daylight saving time?
Yes. Every result uses the actual timezone database, so offsets change automatically where DST applies.
Which zones are available?
40+ zones covering the Americas, Europe, Africa, the Middle East, Asia and Oceania.
Is anything sent to a server?
No - conversions are computed locally with the Intl API.
