How to use
What is a Unix timestamp?
A Unix timestamp is the number of seconds elapsed since 1 January 1970 00:00:00 UTC. It is used universally in programming, databases and APIs. Millisecond timestamps (13 digits) are also detected and converted automatically.
Convert in both directions
Paste a timestamp to get the readable date in multiple formats — local time, UTC, ISO 8601 and relative time. Or switch to Date → Timestamp to convert any date and time back to a Unix timestamp. The live counter at the top shows the current timestamp updating every second.
