How many days from May 15 2025 is May 25, 2025?

Exactly 10. The count starts the day after May 15, 2025 and ends on May 25, 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 May 24, 2025 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
