Convert a travel itinerary time between time zones
Convert a planned local departure date and time between two IANA time zones, including the destination date change and daylight-saving rules supported by your browser.
Convert a planned local date and time from one location to another. Results are calculated in this browser from its time-zone data; verify departure and arrival times on your carrier or transport operator itinerary.
Examples: Asia/Tokyo, Europe/Paris, America/New_York, or Etc/UTC. Use a location identifier, not a short label such as “CST,” because abbreviations can refer to different zones.
Enter a local date and time and both time zones.
A destination may be on a different calendar date even when converting one instant. If you are planning spending around the itinerary, continue with the trip budget planner and currency worksheet.

Time-zone data and limits
The browser's internationalization implementation supplies the named-zone rules used here. Time-zone rules can change when governments change offsets or daylight-saving policy, and browser or operating-system data may not yet include a recent change. Daylight-saving transitions can also skip local clock times or repeat them; this converter reports those inputs instead of guessing. Verify all travel times with the carrier or transport operator.
How it works
Enter the local date and time, then the source and destination IANA time-zone identifiers. Check the result against your airline or transport operator itinerary.
Good to know
Why can a date change during conversion?
Locations can have different UTC offsets, so the same instant may fall on different calendar dates. The result shows the destination's local date as well as time.
How are daylight-saving changes handled?
The browser applies its available time-zone rules. A local clock time skipped by a clock change cannot identify an instant; a repeated time can identify two instants, so this tool asks you to choose another time. Check the operator's itinerary for travel decisions.
