A Unix timestamp is just a count of seconds, which is great for computers and unreadable for people. Paste a timestamp to see the human date and time, or pick a date to get the timestamp back, with the conversion happening entirely in your browser.

Good to know

Seconds or millisecondsUnix time is counted in seconds, but many systems use milliseconds, which look ten digits longer. Feed the wrong one and you land decades off, so check the length.
It is UTC at heartA timestamp has no timezone of its own; it marks a moment in UTC. The readable date you see is that moment shown in a chosen zone, so mind which one.
The 2038 edgeOlder 32-bit systems cannot hold timestamps past early 2038. Most modern code is fine, but it explains odd dates from legacy systems.
Leap seconds are ignoredUnix time treats every day as exactly 86,400 seconds, so it quietly skips leap seconds. For everyday use this never matters.
