Business Days Calculator
Calculate the number of business days between two dates, excluding weekends.
What is the Business Days Calculator?
This tool counts weekdays (Monday–Friday) between two dates, or finds the date a set number of business days from a start date — useful for estimating project deadlines, shipping windows, or payment terms that are quoted in business days rather than calendar days.
How to use it
- Choose whether you want the number of business days between two dates, or to add business days to a date.
- Enter the relevant date(s).
- Read the result.
This counts Saturdays and Sundays as non-business days but doesn't know about public holidays, which vary by country and region — for a deadline where a holiday might fall in the range, double-check against your local holiday calendar.
