About this tool

This free time converter does two jobs. First, it converts a date and time between any two of the world's IANA time zones — handy for scheduling meetings, calls and launches across regions. Second, it converts Unix (epoch) timestamps to human-readable dates in your local time and UTC, and converts a date back into a Unix timestamp. All calculations use your browser's built-in internationalisation engine, so daylight saving time is handled automatically.

Key features

Any IANA zone

Convert between 400+ time zones your browser supports.

DST-aware

Daylight saving rules are applied automatically for each date.

Unix timestamps

Convert epoch ↔ date in seconds or milliseconds, plus a world clock.

How to use it

  1. 1In the time zone section, pick the source and target time zones.
  2. 2Enter the date and time to convert — the result updates instantly.
  3. 3In the timestamp section, paste a Unix timestamp to see the date in local time and UTC.
  4. 4Or enter a date to get its Unix timestamp in seconds and milliseconds.

Common use cases

  • Scheduling meetings across countries.
  • Converting a log's Unix timestamp to a readable date.
  • Planning a launch time for a global audience.

Frequently asked questions

Does it handle daylight saving time?

Yes. Conversions use your browser's Intl time zone database, which accounts for daylight saving rules for each zone and date.

Does it support Unix timestamps?

Yes. You can convert epoch timestamps (in seconds or milliseconds) to readable dates, and convert any date back into a Unix timestamp.

Which time zones are available?

All IANA time zones your browser supports — typically 400+ zones covering every region in the world.

Private and free. Most of our tools run entirely in your browser, so the data you enter isn't uploaded or stored. There's no sign-up, and there never will be — they're built by the Fusion Trail Solutions team to be genuinely useful.
