A Unix timestamp is a way to track time as a running total of seconds. This count starts at the Unix Epoch on January 1st, 1970 at UTC. This tool helps you convert between these timestamps and human-readable dates.
Examples and limits
Timestamp 0 in UTC corresponds to 1970-01-01 00:00:00. The tool distinguishes seconds from milliseconds and rejects invalid dates, non-numeric values, and unsafe integers; nonexistent local times during daylight-saving transitions are also rejected. Conversion stays in the browser.
How to use
Choose timestamp or date-time mode, enter a value, select a time zone, and convert. Results are calculated locally and are never submitted to a server.
What is Unix Time?
Unix time (also known as Epoch time, POSIX time, seconds since the Epoch, or UNIX Epoch time) is a system for describing a point in time. It is the number of seconds that have elapsed since the Unix epoch, minus leap seconds; the Unix epoch is 00:00:00 UTC on 1 January 1970.
