How many days from September 9 2025 is September 19, 2025?

Exactly 10. The count starts the day after September 9, 2025 and ends on September 19, 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 18, 2025 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
