What is a Unix Timestamp?

A Unix timestamp (epoch time) is the number of seconds that have elapsed since January 1, 1970, 00:00:00 UTC. It is widely used in programming, databases, and APIs to represent points in time as a single number.

Seconds vs Milliseconds

Some systems use seconds (10 digits, e.g. 1708099200) while others use milliseconds (13 digits, e.g. 1708099200000). This tool auto-detects the format based on the number of digits.
