How this count works
The start date counts and the end date does not, unless you choose “Include end date.” That makes a same-date span zero days by default, or one with the option checked.
A reversed span keeps the same magnitude and shows a minus sign. Weekday and weekend totals use the earlier date as the start. Clock changes do not add or remove calendar dates.

A worked example
From February 28 to March 1, 2024 is 2 days with the end date left out. February 29 is part of that span.
