How the Working Days Calculator Works

This tool counts every day between your start and end dates, then subtracts weekends (Saturdays and Sundays) and public holidays for the selected country. The result is the number of actual working (business) days.

Common Uses

  • Project planning: Calculate delivery timelines in business days
  • Leave calculations: Determine how many annual leave days you need
  • Payment terms: Count "net 30 business days" for invoices
  • Legal deadlines: Courts and regulators often count business days

According to the International Labour Organization, the standard working week is 40-48 hours across most of Africa.
