How many days from August 20 2025 is December 18, 2025?

Exactly 120. The count starts the day after August 20, 2025 and ends on December 18, 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 17, 2025 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
