How many days before March 11 2027 is February 18, 2027?
Exactly 21. The count starts the day after March 11, 2027 and ends on February 18, 2027, 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, 2027 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
