Difference Between Inclusive vs. Exclusive Date Calculations
Standard date calculators use Exclusive calculation (e.g. from July 1 to July 31 is 30 days, computed as End Date - Start Date). Inclusive calculation adds 1 day to count both the start date and end date fully (e.g. July 1 to July 31 = 31 calendar days).
