Times are computed by your device’s own clock and timezone database — nothing is uploaded.
How to use World Clock
- Read the live clocks for each city — they tick every second.
- Pick any city in the converter to see its current time and date.
- The offset line tells you how many hours ahead or behind you it is.
About this tool
Coordinating with people in other countries means one constant question: what time is it there? The world clock keeps a wall of live city clocks on one screen, and the converter spells out the exact hour difference to your own timezone.
Daylight-saving changes are handled automatically by your device’s timezone database, so the clocks stay correct all year.
When to use it: calls, travel and coordinating with people in other timezones.
