Leap year - A year which is divisible by 4, but it won't be century. But you have another option that every 4th century should be a leap year. It has 366 days.

February of a leap year has 29 days. so, there are 366 days in a leap year.

Thus, 1 leap year = 366 days = 52 weeks and 2 days. A leap year comes after every 4 years.

Century:- A block of 100 years is called a century. A century has, thus a total of 100 yr.

Thus, each one of the years 1500, 1700, 2200  is  a century.

Example for Leap year - The years 2004, 1948 are leap years. 2001, 2007, 2005 are not a leap year.

Counting odd days -

Rule 1 - Ordinary year = 365 days. It has 52 weeks plus 1 day. So ordinary years has 1 odd day.

Rule 2 - Leap year = 366 days. Totally 52 weeks plus 2 days. Leap year has two odd days.

Rule 3 - 50 years = 38 ordinary years + 12 leap years

Totally = (38x1 odd day) + 12x2 odd days)

Therefore 62 odd days, then separate it in to weeks.

So 8 weeks+ 6 odd days.

For 50 years there will be a 6 odd days.
