Convert a Unix epoch timestamp into a human-readable date, or turn a date back into a timestamp. Handles seconds and milliseconds. Runs entirely in your browser.
Seconds are ~10 digits today; milliseconds are ~13 digits.
What is a Unix timestamp converter? It translates between Unix epoch timestamps and human dates — both directions. A Unix timestamp counts the seconds since 1 January 1970 UTC.
A Unix timestamp is the number of seconds that have elapsed since 00:00:00 UTC on 1 January 1970, known as the Unix epoch. For example, a timestamp of 0 is 1970-01-01 00:00:00 UTC.
Unix timestamps in seconds are usually 10 digits for current dates, while millisecond timestamps are about 13 digits. This tool lets you switch between seconds and milliseconds with a toggle so the date is read correctly.
Pick a date and time, and the tool returns the number of seconds (or milliseconds) since the Unix epoch. The date you enter is read in your local time zone and converted to the epoch count.
