Correct option is D
To find when the calendar of 2024 (a leap year) will repeat:
Leap Year Rule: Leap years repeat every 28 years.
So, Add 28 years to 2024: 2024+28=2052
Reason: 28 years ensure divisibility by 7 (day alignment) and leap year conditions.
Repetition Intervals Summary:
Type of Year | Repetition Interval |
|---|---|
Normal Year | 6 or 11 years |
Leap Year | 28 years |
Centurial Year (Normal) | 6 years |
Centurial Year (Leap) | 400 years |
Thus, correct option is (d).
