How the Business Days Calculator works
The calculator counts each complete week in the range as five business days, then checks the remaining days one by one, counting those that fall on Monday to Friday and skipping Saturdays and Sundays. By default the range excludes the end date, like counting nights in a hotel stay; include it when you need both ends counted.
Public holidays differ by country, state and company, so they are not removed automatically. Subtract any holidays that fall within your range from the result to get the exact number of working days.
