Counting with or without the end date
From Monday to Friday is 4 days apart, but 5 days if you count both Monday and Friday. Hotel stays count nights (no end date); event durations and leave requests often count both days.
Frequently asked questions
How do I count business days?
Use the weekdays line, which counts Monday through Friday. Subtract any public holidays that fall in the range.
What date is 90 days from today?
Use the add-days box. It's handy for return windows, notice periods, and visa or warranty deadlines.
