How many days from December 4 2027 is January 3, 2028?
Exactly 30. The count starts the day after December 4, 2027 and ends on January 3, 2028, 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 January 2, 2028 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.

27 of the 30 days fall in December 2027 and the remaining 3 in January 2028, ending on the 3rd. No leap day falls inside the span, so every month in it has its ordinary length.

| January 2028 | 1 to 3 | 3 | 30 |
