How it works

All conversions use the browser's native Date API: new Date(), .toISOString(), .toLocaleString(), and Date.now(). No server processing, the result appears immediately in your browser.

Processing runs in your browser

Timestamps are converted entirely in your browser tab. Our servers are not involved at any point.

Frequently asked questions

What is a Unix timestamp?
A Unix timestamp is the number of seconds that have elapsed since 00:00:00 UTC on 1 January 1970 (the Unix epoch). It is timezone-independent and widely used in programming and databases.
What is the maximum Unix timestamp?
The maximum 32-bit signed Unix timestamp is 2,147,483,647, which corresponds to 03:14:07 UTC on 19 January 2038. This is the Y2K38 problem. 64-bit timestamps extend this by billions of years.
Can I convert negative timestamps?
Yes. Negative timestamps represent dates before the Unix epoch (before 1 January 1970). For example, -86400 is 31 December 1969.
