How many days before June 17 2025 is March 19, 2025?
Exactly 90. The count starts the day after June 17, 2025 and ends on March 19, 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 20, 2025 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
