How many days before March 31 2025 is March 1, 2025?
Exactly 30. The count starts the day after March 31, 2025 and ends on March 1, 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 2, 2025 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
