How many days before April 7 2026 is March 17, 2026?

Exactly 21. The count starts the day after April 7, 2026 and ends on March 17, 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 March 18, 2026 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
