Day of The Week Without Reference

Ex.  What was the day on 15 Aug, 1947?

Sol.  We know that till year 1600 there were no odd days.

        Till 1900, the number of odd days = 1

        In the next 46 years, every normal year would have 1 odd day, and every leap year would have an additional odd days, that is, 2 odd days.

Hence, from 1901 to 1946 the total number of odd days = 46 + 110 = 57, which is equivalent of 8 full weeks and one extra day i.e. 1 odd day. So, that makes a total of 2 odd days till 1946.
