How many days from July 17 2026 is August 31, 2026?

Exactly 45. The count starts the day after July 17, 2026 and ends on August 31, 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 August 30, 2026 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
