180 days from December 29, 2025 is Saturday, June 27, 2026
Counting forward 180 days from December 29, 2025, a Monday, lands on Saturday, June 27, 2026. The span crosses from 2025 into 2026.
How many days from December 29 2025 is June 27, 2026?
Exactly 180. The count starts the day after December 29, 2025 and ends on June 27, 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 June 26, 2026 instead, one day earlier, and that single day is the most common mistake in deadline arithmetic.

|---|---|---|---|
| December 2025 | 30 to 31 | 2 | 2 |
| January 2026 | 1 to 31 | 31 | 33 |
