How to use it
A Unix timestamp counts the seconds since 1 January 1970 (the epoch), in UTC. Paste a timestamp to see the UTC and local date, or pick a date to get the timestamp back. Choose seconds or milliseconds — ten digits are usually seconds, thirteen are milliseconds. Handy for logs, APIs, databases and debugging.

What is a Unix timestamp?
It is the number of seconds since 1 January 1970, 00:00:00 UTC — the Unix epoch. It stores a moment in time compactly and without a timezone, so it is widely used in logs, APIs and databases.
Seconds or milliseconds?
A 10-digit value is usually seconds; a 13-digit value is milliseconds (common in JavaScript). Switch the unit to match your input — the tool converts both.
Is my data sent anywhere?
No. The conversion happens entirely in your browser; nothing is uploaded.
