How to use the World Clock
- Your own time zone is shown first.
- Add cities from the list.
- Remove any you don't need — your choices are saved on this device.
What does this tool do?
Each clock updates every second and shows the UTC offset in effect today, so daylight saving changes are always reflected.
It's especially handy for remote teams and families spread across countries: at a glance you can see whether it's a sensible hour to call, with day and night shown for each city.
Why use it?
- Work with remote teams and clients.
- Keep in touch with family abroad.
- No account needed to save your cities.
Tip
Combine it with the Time Zone Converter when you need to plan a meeting at a specific future time.

Frequently asked questions
Does it adjust for daylight saving time?
Yes. Each clock uses your browser's time zone database, so daylight saving changes are applied automatically on the right dates for each place.
Will my cities be saved?
Yes. Your chosen cities are saved in this browser, so they're there next time you visit on the same device. Nothing is stored on our servers.
