What a Unix timestamp is
A Unix timestamp counts the seconds since the first of January 1970 in UTC. It is a compact, time-zone-free way for systems to store a moment in time. This tool shows both your local time and UTC so there is no confusion.
date = epoch start + timestamp seconds
A real example
A log line shows 1700000000 and you need to know when that was. Pasting it here gives the readable date in your own time zone, so you can line it up with other events.
Common questions
Seconds or milliseconds?
This tool uses seconds, the most common format. If your value has 13 digits it is milliseconds, so divide by 1000 first.
