How many days from September 15 2026 is September 25, 2026?
Exactly 10. The count starts the day after September 15, 2026 and ends on September 25, 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 24, 2026 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
