How to use it
Choose a start and end date. By default the count excludes the end date, so Monday to Tuesday is 1 day. Tick “include the end date” when counting both days, such as the length of a holiday or a leave period.
Weekdays count Monday to Friday only and do not skip public holidays, which differ by state and country.
FAQ
Does it handle leap years?
Yes, it counts actual calendar days.
