How this tool works
Unix time measures elapsed time from 1970-01-01T00:00:00Z. Seconds multiply by 1,000 to obtain the JavaScript millisecond timestamp.
Example
Convert 0 seconds to the Unix epoch, or choose a date and obtain its epoch value for an API parameter.
Common questions
How can I tell seconds from milliseconds?
Modern millisecond timestamps are usually about 13 digits while seconds are about 10 digits; this tool lets you explicitly select the unit.
What time zone is the Unix timestamp in?
Unix time represents an instant independent of time zone. The page shows both UTC and your browser’s local display.
