Calendar-based aptitude concepts – UGC NET Question

Statements A and B are true because the weekday sequence repeats every seven days and a non-leap year of 365 days shifts the starting weekday by one day in the next year. Statement E is also correct since many calendar questions ask candidates to determine the weekday for a given date. Statement C is false because leap years have 366 days, and D is false because century years must be divisible by 400, not merely by 4, to be leap years. Hence, the combination A, B and E only is correct.

Option A:
Option A is incomplete as it omits E and does not explicitly connect the calendar structure to typical exam tasks that require finding weekdays. Without E, the applied dimension of the topic is missing.

Option B:
Option B is correct because it groups the three true statements about the cyclic nature, year shift and exam usage of calendar facts, while rejecting C and D, which misrepresent leap-year and day-count rules. It thus matches the logical content of NET-level calendar questions.

Option C:
Option C is wrong because it adds C, which incorrectly assigns 365 days to leap years, and still omits D, failing to discuss the additional condition for century years. Including C makes the option factually incorrect.

Option D:
Option D is incorrect since it includes D, the statement that ignores the special rule for centuries, and therefore endorses a mistaken description of the Gregorian calendar. This misclassification invalidates the option.
