How many days before June 30 2026 is June 9, 2026?
Exactly 21. The count starts the day after June 30, 2026 and ends on June 9, 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 June 10, 2026 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
