To determine which year shares the same calendar as 2025, we calculate the total number of odd days from 2025 onward until they sum to 7, resetting the day alignment.

Step 1: Odd days for each year

Year	Type	Odd Days
2025	Common	1
2026	Common	1
2027	Common	1
2028	Leap Year	2
2029	Common	1
2030	Common	1

Total Odd Days = $1 + 1 + 1 + 2 + 1 + 1 = 7$.

When the total odd days equal 7, the day alignment resets, and the same calendar repeats.

The year 2031 has the same calendar as 2025.
