Clock
When to use this tool
Use a world clock to keep a small set of relevant local times visible during a meeting, class, event, or shared screen.
It is a current-time reference, not a meeting scheduler; confirm official event details in the relevant calendar or invitation.
How to use the clock
Read local time
Use the large browser-local clock as your default display.
Set your display
Choose 12- or 24-hour time and show or hide the date.
Add world cities
Compare supported cities and their local-time offsets.
Manage your view
Remove cards you no longer need or choose one for the main clock.
Frequently asked questions
- Does the world clock need a timezone API?
- No. It uses the browser’s timezone formatting support and a bundled city catalog after the site has loaded.
- Should I rely on an old offset near daylight-saving time?
- No. Check the current display again near a daylight-saving transition before confirming an important event.
