How many days before September 1 2027 is August 2, 2027?
Exactly 30. The count starts the day after September 1, 2027 and ends on August 2, 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 August 3, 2027 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
