Counting back 21 days before July 31, 2025, a Thursday, lands on Thursday, July 10, 2025.
How many days before July 31 2025 is July 10, 2025?
Exactly 21. The count starts the day after July 31, 2025 and ends on July 10, 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 July 11, 2025 instead, one day later, and that single day is the most common mistake in deadline arithmetic.
How is 21 days before July 31 2025 calculated?
The whole count stays inside July 2025, which has 31 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.

|---|---|---|---|

Skipping Saturdays and Sundays, 21 working days before July 31, 2025 is Wednesday, July 2, 2025.
