How many days from September 17 2026 is September 27, 2026?
Exactly 10. The count starts the day after September 17, 2026 and ends on September 27, 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 26, 2026 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
