Use Count mode for existing ranges
When you already have a start and end date and want to know how many business days are in between, use Count Work Days.
Use Add mode for deadlines
When a contract or agreement says '10 business days,' use Add Work Days to find the exact calendar date.
Check the weekend count
The breakdown shows how many weekend days fall in your range, which is useful for understanding why a calendar range has fewer work days than you expected.
Works for any length
Count a single week, a month, a quarter, or a full year. The tool handles any date range.

Standard five-day week
The tool uses the standard Monday through Friday work week. If your work week differs, adjust the result accordingly.
