How to use

The current Unix time updates live at the top — click Use Now to copy it into the converter.
To convert a timestamp to a date: paste the number and press Convert. Seconds (10 digits) and milliseconds (13 digits) are auto-detected.
To convert a date string to a timestamp: paste an ISO 8601 string (2024-01-15T12:00:00Z) or just 2024-01-15 and press Convert.
Both UTC and your local time-zone are shown so you don't need to do time-zone math.

Unix time counts seconds since 1970-01-01 UTC, ignoring leap seconds. The 32-bit signed range overflows in 2038 — most modern systems use 64-bit and are unaffected.
