If 11th January 2024 is a Thursday, what was the day on 11th January 2023 ?

The Correct Option is A

Solution and Explanation

Step 1: Understanding the Question
We know the day for 11 January 2024 and must go back one year to 11 January 2023.

Step 2: Count the days between the dates
From 11 January 2023 to 11 January 2024 there is one full year. The year 2023 is not a leap year, and 29 February 2024 falls after 11 January 2024. So the gap is 365 days.

Step 3: Convert to odd days
A week has 7 days. \[ 365 = 7 \times 52 + 1 \]
So there is 1 odd day. The weekday moves ahead by 1 when we go forward one year.

Step 4: Go backward
11 January 2024 is a Thursday. Going back 365 days takes us one weekday back. The day before Thursday is Wednesday. So 11 January 2023 was a Wednesday.

Step 5: Check the other options
Thursday would need 0 odd days, which is only true for a gap of 364 days. Saturday and Sunday would need a shift of 2 or 3 days back, which is not the case here.

Final Answer:
11 January 2023 was a Wednesday, option 1. \[ \boxed{\text{Wednesday}} \]
