Answers

Frequently asked questions

Does the day count include both dates?

No. It reports elapsed days between the date boundaries. For a count that includes both event dates, add one day to the absolute result.

What if the end date is earlier?

The signed result is negative, while the absolute duration is still shown as a positive number.
