How to Use the Time Duration Calculator

Start and end each take both a date and a time — this is the version to use when the gap spans more than a day, unlike the plain Time calculator.

This is the date-and-time version of a day counter — instead of just "how many days between these two dates," it's "exactly how much time between this precise moment and that one," down to the minute. This Time Duration Calculator takes a full date and time at both ends and returns the elapsed days, hours, and minutes, plus the total expressed purely in hours.
