How many days before May 11 2025 is March 27, 2025?
Exactly 45. The count starts the day after May 11, 2025 and ends on March 27, 2025, 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 28, 2025 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
