Working Days Calculator Guide
What is the Working Days Calculator?
The Working Days Calculator counts business days between a start and end date. It is useful for project planning, calculating notice periods, payroll periods, and meeting legal deadlines. The result excludes Saturdays and Sundays.
How to calculate it manually
Count every calendar day between start and end (inclusive). Then subtract Saturdays and Sundays. The remaining count is your working days. For holiday-adjusted results, subtract any public holidays that fall on weekdays within the range.
