Saturday and Sunday are excluded. No country holiday calendar is assumed unless you enter dates yourself.

Add or subtract business days

The calculator skips Saturday and Sunday and can also skip holiday dates that you explicitly enter. This is different from Business Days Calculator, which counts workdays between two endpoints rather than finding an offset date.

No hidden holiday assumptions

Public holidays vary by country, state, employer, school, and contract. The tool therefore never inserts a holiday calendar unless you provide the dates yourself.
