What is a Unix Timestamp?

A Unix timestamp is the number of seconds since January 1, 1970 00:00:00 UTC (the Unix Epoch). It's widely used in programming, databases, and APIs because it's timezone-independent and easy to compare.

Seconds vs Milliseconds

Unix timestamps in seconds have 10 digits (e.g., 1700000000). JavaScript and some APIs use milliseconds with 13 digits (e.g., 1700000000000). This tool auto-detects which format you're using.
