100 days from December 28, 2027 is Thursday, April 6, 2028
Counting forward 100 days from December 28, 2027, a Tuesday, lands on Thursday, April 6, 2028. The span crosses from 2027 into 2028.
How many days from December 28 2027 is April 6, 2028?
Exactly 100. The count starts the day after December 28, 2027 and ends on April 6, 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 April 5, 2028 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.

3 of the 100 days fall in December 2027, the count then runs through January, February and March, and it finishes in April 2028 on the 6th. The span contains a leap day, February 29, 2028, so a calculation that assumed a 365 day year would be one day out.
| Month | Days counted | In month | Running total |
|---|---|---|---|
| December 2027 | 29 to 31 | 3 | 3 |
| January 2028 | 1 to 31 | 31 | 34 |
| February 2028 | 1 to 29 | 29 | 63 |
| March 2028 | 1 to 31 | 31 | 94 |
| April 2028 | 1 to 6 | 6 | 100 |
