What Business Days does

Inclusive of both ends. Choose Sat–Sun, Fri–Sat, or no weekend. No holidays.

Business Days sits in the Date & time group on purpose. It is not Date Difference (Count days, weeks, and calendar span between dates.) and not Age Calculator (Years, months, and days from a birth date.). Choose this page when you need Count weekdays between dates, with weekend options. If you stretch Business Days into a neighbor’s job, the result will look wrong even though the site chrome looks the same.
