How many days from September 29 2026 is October 14, 2026?

Exactly 15. The count starts the day after September 29, 2026 and ends on October 14, 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 October 13, 2026 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
