World Clock

The current time in the cities you care about, updated every second.

Using the world clock

  1. Your own time is shown first, then the default cities.
  2. Add any city, IANA zone, or abbreviation with the box below the grid; remove one with ×.
  3. ☀ and ☾ show whether it is daytime (6 AM–8 PM) there. The offset shows how far ahead or behind you each city is.

Your list and 12/24-hour choice are saved in this browser only.

Frequently asked questions

Are the world clock times accurate?

They use your device clock plus the IANA time zone rules built into your browser, including daylight saving. If your device clock is correct, every city is correct.

Will my cities be remembered?

Yes, the list is saved in this browser's local storage. Nothing is uploaded, and Reset cities restores the defaults.
