Unix timestamp converter

Convert Unix timestamps and dates

Logs, databases and APIs often store time as a Unix timestamp: the number of seconds since 1 January 1970 (UTC). This converter turns a timestamp into a readable date and turns a date back into a timestamp.

Paste a timestamp to see the date in UTC and in your local time zone, or pick a date to get its timestamp. A 13-digit number is usually in milliseconds rather than seconds.

Conversion happens in your browser. Free, with no sign-up.
