- Or pick a date and copy the timestamp it produces.
The Unix epoch
Timestamp 0 in seconds is 1 January 1970 at 00:00:00 UTC. One day later is 86400. A millisecond timestamp for the same epoch is 0 as well, and one second later is 1000.
Unix time counts seconds since 00:00:00 UTC on 1 January 1970, ignoring leap seconds. JavaScript and many APIs use milliseconds, which are that count times 1,000. A 10-digit number is almost always seconds. A 13-digit number is almost always milliseconds. This page lets you force either interpretation so a value is not guessed wrong. Dates you type are read as local time on your device, and the result shows both that local reading and UTC.
