Frequently asked questions
Are both dates included?
The day count is exclusive of the start date; working days are counted inclusively so a Monday-to-Friday week shows 5.
Why don't months divide evenly?
Months are 28–31 days long, so calendar months are counted by the calendar, not by dividing days by 30.
