What a Unix timestamp is for

Most computer systems store a date as a plain number, the Unix timestamp, rather than text: more compact, easier to compare and sort. This number represents the time elapsed since a shared origin point, January 1, 1970.

What this tool does not do

This tool only applies the calculation described, with no check on the context of use. No limit is set by the tool itself; the only constraint is your device's memory.

Frequently asked questions

Why do some timestamps have so many digits?

A timestamp in milliseconds has three more digits than one in seconds: 1000 milliseconds equal 1 second. JavaScript, among others, uses milliseconds.

Is my data sent to a server?

No: the text you type or paste is processed entirely in your browser, on your device. It is never transmitted to a server.

Do I need to create an account or install anything?

No: the tool works directly in this page, with no sign-up and nothing to install.
