How many days before May 4 2027 is March 20, 2027?

Exactly 45. The count starts the day after May 4, 2027 and ends on March 20, 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 March 21, 2027 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
