How Unix time works
A Unix timestamp counts the seconds since 1 January 1970 UTC. Many systems use milliseconds instead, so this tool detects the unit for you.
Date calculator →Common questions
What is a Unix timestamp?
The number of seconds since 1 January 1970 at 00:00 UTC, also called the epoch.
Seconds or milliseconds?
Ten digits is usually seconds, thirteen is usually milliseconds. The tool detects the unit from the size of the number.
Does the time zone change the timestamp?
No. A timestamp is the same moment everywhere. The time zone only changes how the date is written.
What happens in 2038?
Systems that store seconds in a signed 32-bit number overflow on 19 January 2038. Modern systems use 64 bits.
