Timezone converter
Convert a time between zones — daylight saving handled correctly, on your device.
Pick a date, a time, and two zones to see the matching wall-clock time in the target zone, its UTC offset, and whether it lands on the previous or next day. Daylight-saving transitions are handled correctly using your device time-zone database, so summer and winter offsets are right.
How it works
- Pick the date and time.
- Choose the source zone.
- Choose the target zone.
- Read the converted time and offset.
Example uses
- Scheduling a call between Warsaw and New York.
- Checking when a livestream starts in your zone.
- Planning a flight arrival across time zones.
Frequently asked questions
Does it handle daylight saving?
Yes. The offset is read from your device time-zone database for the exact date, so a summer time and a winter time convert differently — as they should.
Why does the day sometimes change?
When the target zone is far enough ahead or behind, the same instant falls on the previous or next calendar day. The result shows that shift.
