How many days before October 24 2027 is October 3, 2027?
Exactly 21. The count starts the day after October 24, 2027 and ends on October 3, 2027, which is the convention almost every contract and deadline uses: the start date is day zero, not day one. Counting the start date as well would give October 4, 2027 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
