How to use Time zones
- 1. Read the table. UTC plus regional capitals.
- 2. Watch DST names. Long names change with the season.
- 3. Copy a zone id. Use it in servers, not abbreviations.
- 4. Compare with Unix tool. For a specific epoch.
About this tool
Abbreviations like IST are ambiguous. IANA names are not. This explorer shows what this browser thinks each zone is right now.
Source of truth
The browser's ICU/CLDR data. Keep the OS updated.
Not a meeting planner
No calendar math beyond now.
Addresses to coordinates
Need lat/long from a place name first? See the free geocoding API comparison (Nominatim, Google, Mapbox) in API guides — then compare zones here.
