120 days from June 1, 2026 is Tuesday, September 29, 2026
Counting forward 120 days from June 1, 2026, a Monday, lands on Tuesday, September 29, 2026.
How many days from June 1 2026 is September 29, 2026?
Exactly 120. The count starts the day after June 1, 2026 and ends on September 29, 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 September 28, 2026 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
