CorrectNot quiteAnswer B
Correct answer: B
Explanation
Odd days carried from each year: 2024 is leap (2), 2025 (1), 2026 (1), 2027 (1), 2028 is leap (2).
Running total: 2, 3, 4, 5, 7. It reaches 7 after 2028.
So 1 January 2029 is a Monday.
Worth noting
2052 is when the whole 2024 CALENDAR repeats (28 years). The question asks only about 1 January. 2031 treats every year as 1 odd day.
