Convert Unix epoch timestamps to readable dates, and any date back to a timestamp. Live current timestamp updated every second.
Unix time (a.k.a. POSIX time or epoch time) is the number of seconds elapsed since January 1, 1970, 00:00:00 UTC, not counting leap seconds.
It's used universally in programming, databases, and APIs because it's timezone-independent and simple to compare and calculate with.
32-bit systems that store timestamps as a signed integer will overflow at 2,147,483,647 — January 19, 2038. Most modern 64-bit systems are not affected.
