Weekdays are not always working days
A basic business-day calculation usually removes Saturdays and Sundays. Public holidays, company shutdowns and regional workweeks can change the true number of working days, so add those rules separately when they matter.
Planning deadlines with business days
Business-day counts are useful for shipping estimates, payment terms and project deadlines. When a contract or government rule defines a business day, use that exact definition rather than assuming every Monday through Friday qualifies.
