Counting back 14 days before October 1, 2025, a Wednesday, lands on Wednesday, September 17, 2025.
How many days before October 1 2025 is September 17, 2025?
Exactly 14. The count starts the day after October 1, 2025 and ends on September 17, 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 September 18, 2025 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
How is 14 days before October 1 2025 calculated?
The whole count stays inside September 2025, which has 30 days, so no month boundary is crossed at all. No leap day falls inside the span, so every month in it has its ordinary length.

|---|---|---|---|
| September 2025 | 17 to 30 | 14 | 14 |

Skipping Saturdays and Sundays, 14 working days before October 1, 2025 is Thursday, September 11, 2025.
