How many days before October 22 2025 is September 7, 2025?

Exactly 45. The count starts the day after October 22, 2025 and ends on September 7, 2025, 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 September 8, 2025 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
