How many days from December 14 2025 is December 29, 2025?
Exactly 15. The count starts the day after December 14, 2025 and ends on December 29, 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 December 28, 2025 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
