- Leap Year:(i). Every year divisible by 4 is a leap year, if it is not a century.(ii). Every 4th century is a leap year and no other century is a leap year.Note: A leap year has 366 days.Examples:
- Each of the years 1948, 2004, 1676 etc. is a leap year.
- Each of the years 400, 800, 1200, 1600, 2000 etc. is a leap year.

- 1 ordinary year = 365 days = (52 weeks + 1 day.)
1 ordinary year has 1 odd day.
- and 1 leap year = 366 days = (52 weeks + 2 days)
1 leap year has 2 odd days.
- 100 years = 76 ordinary years + 24 leap years = (76 x 1 + 24 x 2) odd days = 124 odd days. = (17 weeks + days)
5 odd days.
Number of odd days in 100 years = 5.Number of odd days in 200 years = (5 x 2)
3 odd days.Number of odd days in 300 years = (5 x 3)
1 odd day.Number of odd days in 400 years = (5 x 4 + 1)
0 odd day.Similarly, each one of 800 years, 1200 years, 1600 years, 2000 years etc. has 0 odd days.
