How many days before October 11 2026 is July 13, 2026?
Exactly 90. The count starts the day after October 11, 2026 and ends on July 13, 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 July 14, 2026 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
