What this calculator estimates
Add business days to a start date while skipping Saturdays and Sundays.
Inputs and units
Enter Start year, Start month, Start day, Business days to add. Use the units shown. Required fields cannot be blank. Use zero only where that field and the model allow it. Select Calculate after changing the values.
Method and assumptions
Move forwards or backwards by the entered whole number of Monday-to-Friday days. The starting day is not counted. Saturdays and Sundays are skipped. The output also counts all calendar days traversed and the weekend days skipped.
Worked example
Friday October 16, 2026 plus one business day is Monday October 19. Saturday October 17 plus five business days is Friday October 23. Entering zero leaves the starting date unchanged.
Limitations
Public holidays, regional Friday/Saturday weekends and business-specific closures are not included. Output dates must fall between years 0100 and 9999.
