How many days before March 11 2025 is February 9, 2025?
Exactly 30. The count starts the day after March 11, 2025 and ends on February 9, 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 February 10, 2025 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
