How many days before October 19 2025 is July 21, 2025?
Exactly 90. The count starts the day after October 19, 2025 and ends on July 21, 2025, 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 22, 2025 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
