A Unix timestamp is the number of seconds elapsed since 1 January 1970 (UTC). Convert in both directions. Runs entirely in your browser.

This Unix timestamp converter turns a Unix timestamp into a readable date, and a date into its Unix timestamp, in either direction.

Two ways to convert

Type a Unix timestamp (in seconds) to see it as a local date, or pick a date and time to get its Unix timestamp. The result also shows the UTC time and the value in milliseconds, useful when debugging APIs or databases that store timestamps in different units.

FAQ

What is a Unix timestamp?
It's the number of seconds elapsed since 1 January 1970 at 00:00:00 UTC, also known as the Unix epoch. It's used across programming languages and databases to store dates as a single number.
Does the converter use my local time zone?
Yes. The date field shows your local time, while the breakdown also shows the equivalent UTC time and the value in milliseconds.
Is my data sent to a server?
No. The whole conversion runs in your browser using JavaScript's built-in date functions, so nothing you enter leaves your device.
