Leap Day

Today is a leap day yay! I actually didn't even realize this year was a leap year until today...

Did you know numbers can be happy?  Happy numbers... they're number that if you keep squaring the digits and adding them together, you'll get 1 at the end.  For example 28,
2^2 + 8^2 = 70
7^2 + 0^2 = 49
4^2 + 9^2 = 97
9^2 + 7^2 = 130
1^2 + 3^2 + 0^2 = 10
1 ^2 + 0^2 = 1
yay it's a happy number.
Poor 29 isn't happy... it's probably sad because it only in February once every 4 years... except on centuries unless that century is a 4th century... gosh leap years are so complicated.
