How many days before May 26 2026 is May 5, 2026?
Exactly 21. The count starts the day after May 26, 2026 and ends on May 5, 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 May 6, 2026 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
