How many days before May 11 2026 is January 11, 2026?
Exactly 120. The count starts the day after May 11, 2026 and ends on January 11, 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 January 12, 2026 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
