What is the Business Days Calculator?
Count weekdays between two dates while excluding Saturdays and Sundays. ITS Research Solution keeps the interactive tool above the explanation so you can calculate first and then review the method used.
Formula or method
Each calendar date in the selected interval is checked for Monday through Friday.
How to use this tool
Enter the requested values using consistent units, run the calculation and review the main result plus any supporting values. A Monday-to-Friday workweek contains five business days when both endpoints are included.
Interpretation and limitations
Public holidays are not automatically excluded because holiday calendars differ by country and organization. Always check source data, units, rounding and discipline-specific requirements before using a result in assessed, published, regulated or high-stakes work.
