On 7th March, 2005 Monday falls. What was the day of the week on 7th March 2004?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Sunday
A weekday moves forward by the number of odd days (days left over after whole weeks) in the time between two dates. An ordinary year of 365 days is 52 weeks + 1 day; a period that contains 29 February has 366 days, which is 2 odd days.
From 7 March 2004 to 7 March 2005, the only February is February 2005, which has 28 days (29 February 2004 came before 7 March 2004)
So the period has 365 days, that is, 1 odd day
7 March 2005 is a Monday, so 7 March 2004 was one day earlier: Sunday
Tip: 2004 is a leap year, but its extra day matters only if 29 February falls between the two dates; here it does not, so the answer is not Saturday.
