What is the Unix Timestamp Converter?

The Unix Timestamp Converter translates epoch time into human-readable dates and back. Paste a timestamp in seconds or milliseconds to see it in ISO 8601, UTC, your local time zone and relative form like "3 hours ago", or enter a date to get its Unix value for logs, databases and API payloads.

How to use it

  1. Paste a timestamp or pick a date.
  2. Read the ISO, UTC, local and relative values.
  3. Copy the format you need.

Features

  • Seconds and milliseconds detected
  • ISO 8601, UTC and local time output

  • Date to epoch conversion

Frequently asked questions

What is a Unix timestamp?

It is the number of seconds that have passed since 1 January 1970 00:00:00 UTC, known as the Unix epoch. Many systems, including JavaScript, use milliseconds instead of seconds.

How can I tell seconds from milliseconds?

Current timestamps in seconds have 10 digits, while millisecond timestamps have 13. The converter detects which one you pasted.
