How many days before September 2 2027 is May 5, 2027?

Exactly 120. The count starts the day after September 2, 2027 and ends on May 5, 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 May 6, 2027 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
