- Friday
Show the answer and the worked solution
Correct answer: B. Wednesday
Worked solution
- From 15 March 2027 to 15 March 2028 spans 366 days, because 29 February 2028 falls inside it.
- 366 ÷ 7 leaves a remainder of 2.
- Two days after Monday is Wednesday.
Answer: Wednesday.
The idea
An ordinary year advances the weekday by 1 and a leap year by 2. What matters is whether 29 February falls inside the interval, not which year is a leap year.
Shortcut. 52 weeks (364 days) after 15 March 2027 is Monday 13 March 2028, because the leap day pulls the date back one; 15 March is two days later, Wednesday.
Common trap. "Tuesday" — adding one day because 2027 is not a leap year, missing that the span runs past 29 February 2028.
