This question was previously asked in
UPSSSC PET 2025 Question Paper (07-Sep-2025) (Shift-2)
The correct answer is

Thursday

To determine what day of the week December 31st falls on in a leap year starting on a Wednesday, we need to apply some logical steps. In a leap year, there are 366 days.

Here's how we solve this problem:

  1. 366 days in a leap year are divided into 52 weeks and 2 extra days. This is because 366 \div 7 = 52 weeks and 2 days.
  2. The extra 2 days will determine the deviation from the start day.
  3. If the first day of the year is a Wednesday, adding the two extra days leads us to 2 days after Wednesday.
  4. Counting from Wednesday:
    • Thursday (first day after Wednesday)
    • Friday (second day after Wednesday)
  5. Therefore, the day on December 31st of that leap year will be a Friday.

Hence, the correct answer, taking into account the increment is Friday, not Thursday as stated in the question's correct answer.
