Find the exact time zone for any coordinates on Earth.
How this tool works
The point is looked up against the authoritative time zone boundaries via the free Open-Meteo service, which returns the IANA zone name (like America/Denver), and your browser then computes the current local time and UTC offset for it. If the service is unreachable, the tool falls back to the nearest listed city's zone, clearly labeled as approximate. Uses your device GPS with one click (your location is processed in your browser and never stored), or you can type coordinates or click the map.
What you can do with it
- Determine the zone for remote coordinates, ships' positions, or field sites
- Get the proper IANA zone name for use in software and calendars
- Check the current local time and offset at any point
- Resolve zones near boundaries where guessing by longitude fails
Why use it
Time zone boundaries follow politics, not meridians, so you cannot compute them from longitude. A boundary-accurate lookup returning the standard IANA name is the correct tool, and this one needs no key.
