Convert Unix time to dates and back
Paste a Unix timestamp — seconds, milliseconds, microseconds or nanoseconds, told apart by digit count — to see it as a UTC string, your local time, an ISO 8601 string and a relative time ("3 days ago"). Or type a date to get the timestamp back in seconds and milliseconds. A live epoch clock ticks at the top, a "Now" button fills the current epoch, and you can render any timestamp in any time zone. The "Interpret number as" menu also reads a Windows FILETIME, a Mongo ObjectID and an Excel serial, and on Auto it takes a written date too — with FILETIME, ObjectID and Excel serial rows in the output. Everything is computed locally in your browser. To turn a phrase like “3 hours ago” back into a moment, or to see the whole gap broken into calendar units, use the Time Ago Calculator.
Frequently asked questions
Does it handle both seconds and milliseconds?
Yes, and microseconds and nanoseconds too. Up to 10 digits is read as seconds, up to 13 as milliseconds, up to 16 as microseconds and up to 19 as nanoseconds, and the Read as line says which it picked.
Can I convert a timestamp into a specific time zone?
Yes. Pick a zone from the time-zone dropdown and the date is formatted for that zone using your browser's built-in Intl engine, while UTC, ISO 8601, RFC 2822 and epoch-milliseconds are shown alongside — all client-side.
