How days are counted
By default the count runs from the start date up to, but not including, the end date, which is the usual way to measure an interval. Tick the box to include both days, for example when counting the days of a trip or a rental.
Business days
The business day count covers Monday through Friday and does not remove public holidays, which vary by employer and state. For legal or contractual deadlines, check the calendar that applies to you.
