What is a Unix Timestamp?

A Unix timestamp (also called Epoch time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It is the most common way to represent date and time in programming, databases, and APIs.

For example, the Unix timestamp 1700000000 represents November 14, 2023 22:13:20 UTC.

Seconds vs Milliseconds

Most Unix timestamps are in seconds (10 digits). JavaScript uses milliseconds (13 digits). Our converter auto-detects which format you entered. You can also see both values in the result.
