How to use Unix Timestamp Converter

Enter a Unix epoch timestamp, and the tool converts it to a human-readable date in both UTC and your local time zone — or enter a date to convert it back.

Frequently asked questions

What is a Unix timestamp?

It is the number of seconds that have elapsed since 00:00:00 UTC on January 1, 1970 (the Unix epoch), a standard way computers store time.

Seconds or milliseconds?

Unix timestamps are traditionally in seconds; JavaScript and many APIs use milliseconds. This tool auto-detects and lets you choose the unit.

What time zone is used?

The tool shows both UTC and your device's local time so you can read the timestamp either way.
