How to count the days between two dates
Count the days from the start date up to the end date. Most people do not count the start day itself. For example, from January 1 to January 10 is 9 days. If you want to count both the first and last day (for example, the length of a trip or an event), tick "Include the end date" and the answer becomes 10.
Business days
Business days are Monday to Friday. This calculator does not remove public holidays, so subtract any holidays that fall in your date range yourself.
