What day of the week was June 7 1970?

Answer 1

1 ordinary year = 365 days= (52weeks + 1day)

An ordinary year has 1 odd day

1 Leap year =366 days= (52weeks + 2days)

A leap year has 2 odd days

100 years= 76 ordinary years + 24 leap years

= [(76x52)weeks + 76days] + [(24x52)weeks + 48 days)

=5200weeks + 124days

=(5217weeks + 5days)

Number of odd days in 1600 years: 0

Number of odd days in 300 years: 2 days

Number of odd days in 70 years:

9 leap years+ 60 ordinary years

9*2+60*1=18+60=78 odd days(11 weeks+1 odd day)

Number of Odd days from 1st Jan,1970 to June 7th 1970:(1+1+5=7)which Implies 0 odd days
