Time Zone Converter
Convert times between IANA time zones, DST-accurate.

Time in target zone

Offset difference
The zone list comes from your browser’s own IANA database, so daylight-saving rules are exact for the chosen zones and date — including the DST dates that trip up manual UTC math.
How to use the Time Zone tool
- Enter your time zone in the fields above.
- Adjust any slider or type an exact number — the answer updates as you go.
- Copy the result and close the tab. Nothing you entered was sent anywhere.
About the Time Zone tool
Pick a date, time and two IANA zones to see the meeting time converter result with the full offset names — using your browser’s own timezone database, so DST rules are exact.
The two-pass DST handling means dates inside DST transitions (spring-forward gaps) resolve sensibly rather than shifting by an hour unnoticed.
Everything runs locally in your browser: no data is uploaded, no account is needed, and it works offline once the page has loaded.
