How many days from January 17 2026 is February 1, 2026?
Exactly 15. The count starts the day after January 17, 2026 and ends on February 1, 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 31, 2026 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
