Explanation:
17th June, 1998 = (1997 years + Period from 1.1.1998 to 17.6.1998)
Odd days in 1600 years = 0
Odd days in 300 years = (5 x 3)

97 years has 24 leap years + 73 ordinary years.
Number of odd days in 97 years ( 24 x 2 + 73) = 121 = 2 odd days.
Jan. Feb. March April May June (31 + 28 + 31 + 30 + 31 + 17) = 168 days
168 days = 24 weeks = 0 odd day.
Total number of odd days = (0 + 1 + 2 + 0) = 3.

Q. How to find number of odd days in 300 years?
Solution:
First number of odd days in 100 years = 98 ordinary years + 2 leap years (2 leap years means: 2*2 = 4 odd days).
1+4 = 5 odd days.
100 years had 5 odd days.
300 years had = 5 odd days*3.
= 15 odd days = 7*2 +1.
= 0+1 (7 days = 0 odd days so, 7+7= 0+0 = 0 odd days = days).
= 1 odd days.
