How many days before December 12 2026 is November 21, 2026?
Exactly 21. The count starts the day after December 12, 2026 and ends on November 21, 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 22, 2026 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
