How it works

  1. Choose the direction.
  2. Enter a timestamp (unit is detected automatically) or a date and time.
  3. Click “Convert” – local time, UTC, ISO 8601 and the relative time appear.

Notes and limitations

  • A Unix timestamp counts the seconds since 1 January 1970, 00:00:00 UTC. Leap seconds are not counted.
  • The unit is detected from the number of digits: 10 digits = seconds, 13 = milliseconds, 16 = microseconds. You can also choose it manually.
  • Local time uses your device’s time zone, including daylight saving time.

Frequently asked questions
