Step-by-Step Worked Example
Inputs: * Start Date = Thursday, October 1, 2026 * End Date = Thursday, October 15, 2026 * Exclude Holidays = None Calculation: * Step 1: Count total days in range = 14 calendar days * Step 2: Identify weekend days: Oct 3, 4, 10, 11 (4 days total) * Step 3: Subtract weekend days: 14 - 4 Result: * Business Days = 10 working days What This Means: There are exactly 10 working business days in this date range, representing two full work weeks.
