Does it count business days only, or exclude the end date?
No - it is a plain calendar-day count. Every day between the two dates is included, weekends and all, and the end date itself is not excluded. If you need a business-day-only count that skips Saturdays and Sundays, this calculator does not offer that - it only computes a straight calendar-day difference.
