How dates are counted
Elapsed days exclude the start date: the same date gives 0. Including both endpoints gives 1 for the same date. The end date must be on or after the start date. Dates use the Gregorian calendar without a time zone or clock time.
To count selected working weekdays and your own closures, use the business-day counter. To create a list, use the date sequence generator.
