How many days before December 16 2026 is November 25, 2026?
Exactly 21. The count starts the day after December 16, 2026 and ends on November 25, 2026, 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 November 26, 2026 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
