How it works

What the calculator is doing

Enter the start date and end date for the range you want to measure.

Choose whether to exclude weekends or count all days in the date span.

The calculator shows both the total calendar days and the effective business days in that inclusive range.

Understanding your result

The key benefit is clarity. It helps show how a date span that looks long on the calendar can shrink once weekends are removed, which is often what matters for paperwork, timelines, and planning around the workweek.
