About the Unix Timestamp Converter

Content reviewed 6 August 2026

A Unix timestamp is the number of seconds since 1 January 1970 UTC — the way servers, logs, and APIs store time. This converts a timestamp into a readable local and UTC date, or turns any date back into a timestamp.

Indispensable when reading server logs, debugging an API, or setting a time field that expects epoch seconds or milliseconds.

Frequently asked questions

Seconds or milliseconds?+

Unix timestamps are classically in seconds (10 digits around now), but JavaScript and many APIs use milliseconds (13 digits). This tool detects the length and converts either — check which your system expects.
