Business day calculator
Working Days Calculator
Count working days between two dates, or add and subtract working days from a start date using region-specific public holidays and configurable weekend days.
Example: use New South Wales, exclude public holidays and keep Saturday/Sunday selected to calculate how many working days sit between a school term date and Australia Day.
Sources and limitations
Public holidays come from the central holiday dataset used by this site. Regional public holidays are applied when they are present in that dataset; school-specific student-free days are not treated as public holidays.
The calculator uses civil calendar dates, not UTC timestamps. It does not store your calculation or create indexable result URLs.
