Frequently asked questions
Should I include the end date?
Include it when counting days of an event that covers both dates, such as a hotel stay counted in days or a leave request. Leave it out to count the gap between two dates.
How are business days counted?
Business days are Monday to Friday. Public holidays differ by country and are not subtracted, so check your local calendar.
