Enter a Unix timestamp or a date below to instantly convert between them - entirely in your browser, nothing is sent to our servers.

A Unix timestamp counts the seconds that have passed since 1 January 1970 00:00:00 UTC. The converter accepts both seconds (10 digits for current dates) and milliseconds (13 digits, the format JavaScript uses), and shows the matching date in UTC and ISO 8601 format; converting a date back gives both the seconds and milliseconds value. A timestamp has no time zone of its own - the same number refers to the same instant everywhere in the world. JustChecker builds tools that respect your data - this one never leaves your browser.
