Convert Date to Seconds

Quickly convert calendar dates to their UNIX timestamp equivalents with the Convert Date to Seconds Tool. This converter takes one or more dates in YYYY-MM-DD format and transforms each into the number of seconds elapsed since the UNIX epoch (1970-01-01 00:00:00 UTC). It’s perfect for working with time-based data, databases, or timestamp calculations.
