How to use the Business Days Calculator
- Choose the start date and the number of business days.
- Choose whether to add or subtract, the weekend days and any holidays.
- Read the resulting date and the calendar days it spans.
Useful for payment terms, notice periods and shipping estimates such as “delivered within 5 business days”. The start date itself is not counted; counting begins on the next business day. Weekends and the holidays you enter are skipped.
