To calculate the number of working days between two dates, start by excluding weekends (Saturday and Sunday). Then, if needed, subtract any holidays that fall on weekdays. This is often done in spreadsheets with formulas like NETWORKDAYS or by counting forward day by day. The result is a simple, precise number that helps with project planning, pay calculations, or deadline tracking.
