If 1st January 2023 was a Sunday, what day of the week was 1st January 2024?

Explanation

The supplied official calendar page is for January 2024, and the reasoning follows the standard odd-days method. Since 2023 was not a leap year, it had 365 days. That is 52 complete weeks plus 1 extra, or odd, day. Complete weeks do not change the weekday, so only the one odd day matters. Starting from the given fact that 1 January 2023 was a Sunday, moving ahead by one odd day makes 1 January 2024 a Monday. This is why the answer is not found by memorising a calendar but by reducing the year to its weekday shift.

Why the other options are wrong

• (A) Sunday would be possible only if 2023 contributed zero odd days, but a 365-day year leaves one odd day after 52 full weeks.
• (C) Tuesday would require a two-day shift, which would match a leap-year span of 366 days, not the non-leap year 2023.
• (D) Saturday moves one day backward from Sunday, whereas the year-to-year shift here moves one day forward.

Concept

This tests calendar reasoning through odd days: converting a year into complete weeks plus the leftover weekday shift. It recurs in RAS mental ability because it checks compact arithmetic and logical sequencing without lengthy calculation.
