How many days before February 11 2025 is January 12, 2025?

Exactly 30. The count starts the day after February 11, 2025 and ends on January 12, 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 13, 2025 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
