91/7 = 13, remainder 0. So, when we go back 3 months, we will end up in a sunday exactly
ganeshie8 (ganeshie8):
03/31 is a sunday
ganeshie8 (ganeshie8):
subtract 7 from 31... and do it until u reach the start of month
OpenStudy (anonymous):

after doing this, we need to go back 5 years
ganeshie8 (ganeshie8):
since 03/31 is a sunday, 03/24, 03/17, 03/10, 03/03 also would be sundays
in 2013
OpenStudy (anonymous):
Its been long procedure...better to calculate odd days for 2008 and added to the month march date..which can exactly divided by 7
ganeshie8 (ganeshie8):

Next, having know 03/31 in 2013 is a sunday, you need to go back exactly 5 years :- 5x365 + 1 = 1826 days to land in 03/31 in 2008.
ganeshie8 (ganeshie8):
1826/7 = something, remainder 6
OpenStudy (anonymous):
yes
ganeshie8 (ganeshie8):
so, you need to go back one more day to land in sunday :- 03/30/2008 is a sunday
ganeshie8 (ganeshie8):
now we keep subtracting 7 from 30 :-
03/23, 03/16, 03/09, 03/02
