What is Leap Year:
(1) A particular year divisible by 4 is called leap year, it should also not BE year century
Eg. the 1976th, 1.84 thousand As they are divisible by 4 are leap year
(2) Each FOURTH century is a leap year
Eg. 400, 800, 1 200, in 1600, 2000th, 2 400 are leap years, but 700, 1,300th, 1 900 are not leap years
What is Odd Days: For a given number of days, number of days are called more than odd days Complete week.
Eg. in 10 days, there is One week and 3 odd days.
How to Counting of weeks and days in year:
(A) 1 Ordinary year has 365 days = 52 Weeks + 1 odd Day
(B) 1 leap year has 366 days = 52 Weeks + 2 odd days
(C) Ordinary 100 years = 76 years + 24 years = 76 * 1 + 24 * 2 = leap 124 odd days
= 17 weeks + 5 odd days
(D) Since in 100 years, number of odd days are 5
(E) In 200 years, number of 5 * 2 = 10 = 1 week are odd days + 3 odd days, 3 odd days
(F) 5 * 3 = 15 = 2 similarly in 300 years + 1 odd Day Weeks
(G) number of similarly for 400 years * 4 + 1 = 0 odd odd days 5 days, from this we conclude that for 800, in 1200, 1600, 2,000th, 2,400 years odd days will BE Zero
