How many days before March 11 2026 is February 18, 2026?

Exactly 21. The count starts the day after March 11, 2026 and ends on February 18, 2026, 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 19, 2026 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
