How many days before February 18 2025 is January 4, 2025?

Exactly 45. The count starts the day after February 18, 2025 and ends on January 4, 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 January 5, 2025 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
