Common questions
Is the end date included?
The elapsed-day result excludes the end date. Turn on the inclusive option to count both boundary dates.
How are weekdays counted?
Weekdays are Monday through Friday. Public holidays are not removed.
Why is one month not always 30 days?
Calendar months vary from 28 to 31 days, so the calendar result uses actual month boundaries.
