How many days before September 11 2026 is September 4, 2026?

Exactly 7. The count starts the day after September 11, 2026 and ends on September 4, 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 September 5, 2026 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
