How many days before January 2 2026 is October 4, 2025?

Exactly 90. The count starts the day after January 2, 2026 and ends on October 4, 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 October 5, 2025 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
