How many days before September 12 2027 is July 29, 2027?

Exactly 45. The count starts the day after September 12, 2027 and ends on July 29, 2027, 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 July 30, 2027 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
