How to Use the Business Days Calculator
Choose a start date, then either enter a number of business days to add or subtract, or enter a second date to count the business days between the two — the calculator automatically skips weekends in either mode, without requiring any manual weekend-counting.
The Business Days Calculator supports two directions — here's what each one does.
Adding or subtracting business days from a date
Enter a start date and a number of business days, and the calculator returns the resulting date, automatically skipping weekends throughout the count — useful for projecting a deadline or delivery date forward, or checking how far back a required lead time pushes a start date.
Counting business days between two dates
Enter a start and end date, and the calculator returns the number of business days between them, again automatically excluding weekends — useful for checking whether a given span actually satisfies a stated business-day requirement.
