Solution   The year 2012 is a leap year. So, it has 2 odd days.   But, Feb 2012 not included because we are calculating from March 2012 to March 2013. So it has 1 odd day only.   The day on 6th March, 2013 will be 1 day beyond the day on 6th March, 2012. Given that, 6th March, 2013 is Wednesday.   6th March, 2012 is Tuesday (1 day before to 6th March, 2013)   Answer Tuesday
