Unix Timestamp Converter

What Is the Unix Timestamp Converter?

A UNIX timestamp is the number of seconds since January 1, 1970 (UTC). This converter translates between that numeric format and readable date/time strings.

UNIX timestamps appear in API responses, log files, database columns, and JWT tokens. Converting them manually is tedious and error-prone, especially with timezone calculations.
