How many days from January 10 2025 is January 31, 2025?
Exactly 21. The count starts the day after January 10, 2025 and ends on January 31, 2025, 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 30, 2025 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
