Frequently Asked Questions
Is the end date included in the count?
Not by default: from Monday to Tuesday is 1 day. Tick "Include end date" to count both the first and last day.
How are business days counted?
Business days are Monday to Friday. Public holidays are not subtracted because they differ by country.
Does it handle leap years?
Yes. The calculation uses real calendar dates, so February 29 and months of different lengths are counted exactly.
