How many days before May 27 2025 is January 27, 2025?

Exactly 120. The count starts the day after May 27, 2025 and ends on January 27, 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 28, 2025 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
