Gregorian Calendar & Business Day Calculation

Business Days = Total Calendar Days - Weekends (Sat/Sun) - US Federal Holidays

Input:

Start Date: Monday, Oct 5 | End Date: Friday, Oct 30

Output:

20 Working Business Days (excluding 8 weekend days and Columbus Day)

Provides exact business turnaround dates for commercial contracts and legal SLAs.
