15 days from December 22, 2025 is Tuesday, January 6, 2026
Counting forward 15 days from December 22, 2025, a Monday, lands on Tuesday, January 6, 2026. The span crosses from 2025 into 2026. That day is Epiphany, a observance.
How many days from December 22 2025 is January 6, 2026?
Exactly 15. The count starts the day after December 22, 2025 and ends on January 6, 2026, 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 5, 2026 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.
How is 15 days from December 22 2025 calculated?
9 of the 15 days fall in December 2025 and the remaining 6 in January 2026, ending on the 6th. No leap day falls inside the span, so every month in it has its ordinary length.
| Month | Days counted | In month | Running total |
|---|---|---|---|
| December 2025 | 23 to 31 | 9 | 9 |
| January 2026 | 1 to 6 | 6 | 15 |
The running total reaches 15 on January 6, 2026. Because the span crosses the end of 2025, the day of the year resets: December 22, 2025 is day 356 of 2025 and January 6, 2026 is day 6 of 2026.
What is 15 business days from December 22 2025?
Skipping Saturdays and Sundays, 15 working days after December 22, 2025 is Monday, January 12, 2026.

Public holidays are not excluded from either figure, so a contractual deadline in a jurisdiction that excludes them will fall later than January 12, 2026.
