Time Zone Converter

How it works

1. Pick a date and time.
2. Choose the time zone it’s currently in.
3. Choose the time zone you want to convert it to.

Supported formats & limitations

• Input
  A date/time plus two IANA time zone names (e.g. America/New_York).
• Output
  The equivalent local date and time in the target zone.

• Time zone names and daylight-saving rules come from your browser’s own built-in time zone database.
• Very old browsers without full Intl time zone support fall back to a shorter list of common zones.

Frequently asked questions

Does this account for daylight saving time? ›

Yes, the conversion is computed for the specific date you choose, so daylight-saving rules are applied correctly for that date.

Is my chosen date and time sent anywhere? ›

No, the conversion runs entirely in your browser using its built-in time zone data.

Why do time zones use city names instead of abbreviations like EST? ›

Abbreviations like EST are ambiguous and don’t handle daylight saving automatically — IANA names like America/New_York are unambiguous and DST-aware.

Troubleshooting

Why does the result look off by exactly one hour? ›

This usually means the date you picked falls right around a daylight-saving transition in one of the two zones — double-check the date.

Why is my time zone missing from the list? ›

Very old browsers may only support a shorter fallback list of common time zones rather than the full IANA database.
