How many cities are supported in the World Clock?+
We support a vast list of major cities spanning all major global time zones, automatically calculating offsets and Daylight Saving Time (DST) changes.
Is the time synchronized with a central atomic clock?+
The clock displays time based on your system clock adjusted by the calculated timezone offsets. Ensure your computer or phone has 'Set time automatically' enabled for absolute accuracy.
Can I pin multiple cities to compare?+
Yes. You can search and add any city to your custom dashboard. Your list of pinned cities is saved locally in your browser storage so they load automatically next time.
