How this business days calculator works
This calculator counts weekdays between two dates and excludes Saturdays and Sundays. You can also decide whether the starting date and ending date are counted in the result.
Business days = total selected days − Saturdays − Sundays
If you are estimating turnaround time, payroll timelines, shipping schedules, or internal deadlines, this gives you a fast weekday total without needing to count days manually on a calendar.
Examples

Example 3
From Wednesday, April 10 to Wednesday, April 17, the result is 6 business days when both dates are included.
