How many days before September 8 2026 is March 12, 2026?

Exactly 180. The count starts the day after September 8, 2026 and ends on March 12, 2026, 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 March 13, 2026 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
