How many days before December 17 2026 is October 18, 2026?
Exactly 60. The count starts the day after December 17, 2026 and ends on October 18, 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 October 19, 2026 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
