How many days from July 31 2025 is November 8, 2025?

Exactly 100. The count starts the day after July 31, 2025 and ends on November 8, 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 November 7, 2025 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.

How is 100 days from July 31 2025 calculated?

31 of the 100 days fall in August 2025, the count then runs through September and October, and it finishes in November 2025 on the 8th. No leap day falls inside the span, so every month in it has its ordinary length.

Public holidays are not excluded from either figure, so a contractual deadline in a jurisdiction that excludes them will fall later than December 18, 2025.
