About
Compare the local time and UTC offset for two time zones at a selected instant. Daylight saving changes are calculated using the browser’s time-zone data.
Choose two locations and a date and time to see how far apart their clocks are. The tool displays the same instant in both zones, each UTC offset, and whether the second zone is ahead or behind.
What you can do
- Compares two IANA time zones at a chosen instant.
- Shows local time and UTC offset for both locations.
- Uses browser time-zone data for daylight saving changes.
Common uses
- Find a meeting time across countries.
- Plan calls with remote teammates or clients.
- Check whether a deadline crosses midnight in another city.
Frequently asked questions
Does the result account for daylight saving time?
Yes. The browser’s built-in IANA time-zone data determines each offset for the selected date and time.
What does “ahead” mean?
If the second zone is ahead, its local clock shows a later time for the same instant. The displayed difference is based on the two UTC offsets.
