Date & Time Calculators
Business Days Calculator
Add business days to any start date to find a deadline, automatically skipping Saturdays and Sundays.
About the Business Days Calculator
Need to know a deadline that is a set number of business days away? This business days calculator adds working days to a start date and skips weekends, so a net 10 business days payment term or a shipping estimate is easy to pin down.
It is the counterpart to the working-days calculator: instead of counting days between two dates, it projects a future date.
How to use the Business Days Calculator
- Choose a start date.
- Enter the number of business days to add.
- Click Find Date to see the resulting weekday and date.
How the calculation works
Move forward one day at a time, counting only Monday–Friday until the required business days are added
Example
Starting on Friday 5 June 2026 and adding 5 business days lands on Friday 12 June 2026, because the weekend is skipped.
