A business day is any day from Monday through Friday, excluding weekends. The calculator walks through each calendar day in the range from Jan 1, 2027 to Dec 31, 2027 and counts it if it falls on a weekday. The result is the total number of working days in the range.
The total days count (365) includes every calendar day in the range, both weekdays and weekends. The weekend days count (104) is the number of Saturdays and Sundays in the range. Business days plus weekend days equals total days.
For ranges that span a DST transition, the calendar day count is not affected. DST changes the clock time but not the number of calendar days between two dates.
