If January 1 is a Friday, then what is the last day of the month March in a leap year?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Thursday
The weekday repeats every 7 days, so only the odd days, the days left over after whole weeks, move it forward. In a leap year February has 29 days, which is 4 weeks + 1 day.
January has 31 days, 3 odd days: 1 February is Friday + 3 = Monday
February has 29 days, 1 odd day: 1 March is Monday + 1 = Tuesday
31 March is 30 days after 1 March
30 days = 4 weeks + 2 days, so 2 odd days
31 March is Tuesday + 2 = Thursday
