Frequently asked questions
What is a Unix timestamp?
The Unix epoch is 1970-01-01 00:00:00 UTC. A Unix timestamp is the number of seconds (or milliseconds) elapsed since then. It is timezone-independent.
Seconds or milliseconds?
JavaScript uses milliseconds (13 digits) while many APIs use seconds (10 digits). This tool handles both — just pick the unit that matches your value.
How do I convert a date to a timestamp?
Enter a date in ISO format or pick one with the native date input, choose your timezone, and the tool returns the equivalent Unix time.
