Time & date utility
Time Zone Converter
Convert a selected date and time across major time zones, validate offsets, compare cities, and copy results into scheduling notes.
Conversion runs in the browser. Use examples, reset the date, and check DST-sensitive offsets before sending invites.

Time Zone Tips
Use exact dates
Offsets can change with daylight saving time, so validate the actual meeting date rather than using a rough hour difference.
Prefer city zones
City-based IANA zones are more reliable than fixed UTC offsets when DST can apply.
FAQ
How does the converter handle daylight saving time?
It uses browser time zone data, so offsets reflect daylight saving changes for the selected date when the runtime supports that zone.
Can I compare several cities?
Yes. Add target zones to compare meeting times across cities and regions in one view.
Is the time data sent outside the browser?
No. Date selection, conversion, copy-oriented review, and validation are handled locally in your browser.
