In 30 years there are 22 non leap years and 8 leap years are there.
for every non leap year 1 odd day. and for leap year 2 odd days.
total no.of odd days = (22*1) + ( 8 * 2) = 38.
odd days = 38/7 = 3.
sunday – 3 = Thursday.
for every non leap year 1 odd day. and for leap year 2 odd days.
total no.of odd days = (22*1) + ( 8 * 2) = 38.
odd days = 38/7 = 3.
