How to Calculate Business Days

Business days, also known as working days, are the days of the week when most businesses operate. Typically, this includes Monday through Friday, excluding weekends (Saturday and Sunday) and public holidays.

Our calculator automatically excludes weekends and can optionally exclude public holidays for your selected country. This is useful for calculating deadlines, delivery dates, payment terms, and more.

Common Use Cases

  • Calculating payment due dates (e.g., "Net 30" terms)
  • Estimating project deadlines
  • Shipping and delivery time estimates
  • SLA (Service Level Agreement) tracking
  • Payroll and HR calculations
