Count the working days between two dates — Monday to Friday, weekends excluded — for deadlines, shipping, and SLAs.
Counts Monday–Friday as business days and excludes Saturdays and Sundays. It does NOT account for public holidays — subtract those separately for an exact working-day count. General information only.
Deadlines, shipping estimates, and service-level agreements usually run on business days, not calendar days. This walks the range day by day, counting only weekdays — so a "5 business day" turnaround lands on the right calendar date even across weekends.
No — it only excludes weekends. Public holidays vary by country and region, so subtract any that fall in your range for an exact count.
Depends on the convention. "Within 5 business days" usually counts days after today; toggle "include both ends" if your rule counts the start date too.
