Expert Answer
The number of odd days in first 1600 years are 0 (odd days -> days more than complete weeks )
number of odd days in 300 years = 1
number of odd days in 49 years = (12 * 2 + 37 * 1) = 61 days = 5 odd days
total number of odd days in 1949 years = 1 + 5 = 6 odd days
Now look at the year 1950
jan 26 = 26 days = 3 weeks + 5 days = 5 odd days
Total number of odd days = 6 + 5 = 11 => 4 odd days
(odd days - 0 = sunday ; 1 = monday ; 2 = tuesday ;..............)
Therefore, Jan 26th, 1950 was Thursday
number of odd days in 300 years = 1
number of odd days in 49 years = (12 * 2 + 37 * 1) = 61 days = 5 odd days
total number of odd days in 1949 years = 1 + 5 = 6 odd days
Now look at the year 1950
jan 26 = 26 days = 3 weeks + 5 days = 5 odd days
Total number of odd days = 6 + 5 = 11 => 4 odd days
(odd days - 0 = sunday ; 1 = monday ; 2 = tuesday ;..............)
Therefore, Jan 26th, 1950 was Thursday
