Timezone Converter

Compare a moment in time across multiple zones at once.

Showing this moment in each zone:

What does this do?

Pick a moment in time and see what wall-clock time that is in any number of cities. Useful for scheduling meetings across continents, decoding a timestamp in a log, or just answering "what time is it for them right now?"

How do I use it?

  1. Pick the moment with the date/time picker, or click Use now.
  2. Add or change zones with the dropdowns.
  3. The wall-clock time and the current UTC offset update for each zone.

Does this handle daylight saving?

Yes. The math uses the browser's built-in IANA timezone database via the Intl API, so DST transitions for any zone are applied automatically based on the date you pick.

Does my schedule leave the browser?

No. All calculations are local — nothing about your meeting times is sent anywhere.
