How many days from May 1 2025 is May 31, 2025?

Exactly 30. The count starts the day after May 1, 2025 and ends on May 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 May 30, 2025 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
