How many days from May 3 2026 is May 18, 2026?
Exactly 15. The count starts the day after May 3, 2026 and ends on May 18, 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 17, 2026 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
