How Business Days Calculation Works

Business days calculation involves counting only the working days between two dates, typically excluding weekends and public holidays. This calculator uses customizable weekend patterns and allows you to specify holidays to get accurate business day counts.

The calculation iterates through each day from the start date to the end date (inclusive) and counts only those days that don't fall on weekends or specified holidays. This is equivalent to Excel's NETWORKDAYS function.
