On 6th March, 2005 Sunday falls. What was the day of the week on 6th March 2004?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → Saturday
The weekday repeats every 7 days, so only the odd days, the days left over after whole weeks, move it. A period of 365 days is 52 weeks and 1 day, so the same date one year later falls one weekday later; a period of 366 days moves it by two.
From 6 March 2004 to 6 March 2005: 29 February 2004 falls before the start, and 2005 has no 29 February, so the period is 365 days, 1 odd day
So 6 March 2005 is one weekday after 6 March 2004
Going back one day from Sunday gives Saturday
