Convert Unix time to dates and back
Paste a Unix timestamp — in seconds or milliseconds, auto-detected — 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. Everything is computed locally in your browser.
Frequently asked questions
Does it handle both seconds and milliseconds?
Yes. Values with 10 or fewer digits are read as seconds; 13-digit values are read as milliseconds.
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.
