Epoch & Unix Timestamp Converter
Convert Unix timestamps (seconds, ms, µs or ns) to dates in UTC and major time zones, and dates back to epoch. Free and private: runs in your browser.
Paste a timestamp or a date. The unit is detected automatically. Leave it empty for the current time.
Runs entirely in your browser. Nothing you paste is uploaded or stored.
Use cases
- Debug timestamps in logs and API payloads.
- Schedule meetings and releases across time zones.
- Check date handling in code before it ships.
Frequently asked questions
Seconds or milliseconds?
10 digits is seconds (Unix, Python, PHP, most APIs); 13 digits is milliseconds (JavaScript Date.now(), Java).
Is the Epoch & Unix Timestamp Converter free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
Does it handle daylight saving time?
Yes. Conversions use your browser's time zone database (IANA), which applies daylight saving rules for the date you enter.
