Daylight saving windows are approximate month ranges and switch on different dates in different regions — the northern and southern hemispheres shift in opposite seasons, which is why the US–Sydney difference changes twice a year. The converter above uses your browser's timezone database, so it always applies the exact rules for the date you pick.

How to use this tool

  1. Pick the date and time you care about, or use Reset to now.
  2. Choose the starting timezone (your location is detected automatically).
  3. Read the equivalent local time in each city, with a dot showing whether it falls in business hours.

How it works

The tool uses your browser's built-in IANA timezone database (the same one your operating system uses), so daylight saving time shifts are applied automatically for each city on the date you choose.

That matters because DST transitions don't happen on the same dates everywhere — for a few weeks each spring and fall, the usual offset between, say, New York and London temporarily changes.

Frequently asked questions

Does this handle daylight saving time?

Yes. Conversions use the IANA timezone rules for the specific date you pick, so DST is applied automatically — including the awkward weeks when regions switch on different dates.

What do the colored status dots mean?

Green means the time falls in typical business hours (9am–6pm) in that city, amber means early morning or evening (7–9am, 6–9pm), and red means outside those hours.

How do I find a good meeting time across timezones?

Enter your proposed meeting time as the starting time, then scan the table for green dots in every participant's city. Adjust the hour until the overlap works.
