Frequently asked questions
Paste the timestamp into the 'Timestamp → date' box and choose whether it's in seconds or milliseconds. The tool shows your local time, the UTC time, and the ISO 8601 string, which you can copy.
A Unix timestamp is the number of seconds that have elapsed since the Unix epoch — 00:00:00 UTC on 1 January 1970. It's a simple, timezone-free way to store a moment in time, widely used in programming, logs, and APIs.
Unix timestamps are usually in seconds (10 digits for current dates), while JavaScript and many APIs use milliseconds (13 digits). Use the Unit selector to match your value, and the date result updates accordingly.
