Compare the raw weekday count with a holiday-aware business-day count so you can plan staffing, approvals, shipping, and project schedules more accurately.
The holiday-aware count uses public holidays for the selected scope.
Optional. Use a more specific holiday scope when your planning depends on state-level public holidays.
Pick the weekly schedule that matches your team, operation, or market before holidays are removed.
