About Epoch Converter

Convert Unix timestamps (epoch seconds or milliseconds) to human-readable dates and back, in UTC and your local time zone. Essential for reading log timestamps and API date fields.

How to use

  1. Enter a Unix timestamp or pick a date and time.
  2. Choose seconds or milliseconds.
  3. Read the result in UTC and local time.

Frequently asked questions

Seconds or milliseconds?
Unix time is traditionally in seconds; JavaScript uses milliseconds. The tool supports both and shows which it detected.
What time zone is shown?
Both UTC and your browser’s local time zone are displayed so you can compare.
