How many days before January 29 2027 is January 8, 2027?
Exactly 21. The count starts the day after January 29, 2027 and ends on January 8, 2027, 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 9, 2027 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
