Solution   The year 2020 is a leap year. So, it has 2 odd days.   But, Feb 2020 not included because we are calculating from March 2020 to March 2021. So it has 1 odd day only.   The day on 6th March, 2021 will be 1 day beyond the day on 6th March, 2020. Given that, 6th March, 2021 is Thursday.   6th March, 2020 is Wednesday (1 day before to 6th March, 2021)   Answer Wednesday
