About this tool

Made for the task at hand.

Inspect epoch values without mental arithmetic. Timestamps with large magnitudes are interpreted as milliseconds; smaller values are treated as seconds.

How to use

  1. Paste a Unix timestamp or use the current time.
  2. Review the detected unit and formatted dates.
  3. Convert a date input back to epoch seconds or milliseconds.

Common questions
How are seconds and milliseconds detected?

Absolute values of 100 billion or greater are treated as milliseconds; smaller values are treated as seconds.

Does the converter use my timezone?

It shows both UTC and your browser’s local timezone so the distinction stays visible.
