How the day counter calculator works

The counter subtracts one date from the other. By default the start date is day 0 and the end date is counted, so from Monday to Wednesday is 2 days.

Turn on Include the end date to count both ends, which is what you want for things like the length of an event or a hotel stay counted in days rather than nights.
