About this tool
Add the cities you care about and see their current local time, date and UTC offset in one list. Daylight saving is handled by the browser's own time zone database, so the offsets shift on the right dates without any maintenance.

- Do my cities stay next time?
- Yes, the list is kept in this browser on this device.
- Does this tool send my data to a server?
