Home/Date & Time/Business Days Calculator

Business Days Calculator

Count how many working days fall between two dates by excluding every Saturday and Sunday in the range. This is exactly what you need for project timelines, delivery estimates, invoice terms and service level agreements that are measured in business days rather than calendar days. Alongside the working day count it shows the total number of days, how many of those are weekend days, and how many full weeks the span covers, so you get the complete picture in one place. The calculation counts both endpoints inclusively when they are weekdays, matching how most contracts describe a period. Choose your start and end dates and the figures update at once. Everything is computed in your browser, so your schedule stays private and there is nothing to install.
