Current Unix time

About the Epoch Converter

Computers often store time as a Unix timestamp — the number of seconds since 1 January 1970. Convert timestamps (seconds or milliseconds) into readable local, UTC and ISO dates, or turn any date and time back into a timestamp.

When to use it

  • Reading timestamps in logs, databases and API responses
  • Setting expiry times for tokens and cookies
  • Debugging time-zone problems
  • Scheduling events in code

Tips for the best results

  • 13-digit numbers are milliseconds; 10-digit numbers are seconds — both are detected automatically
  • ISO 8601 format is the safest way to share dates between systems
  • The “relative” row shows how long ago or how far ahead a time is

How to use the Epoch Converter

  2. The output is generated instantly in your browser.
  3. Copy or download the result.
