Frustration

Frustrating Fact:

A year is more than 365 days, but less than 365.25, it's actually 365.2425 days.

Which is why year divisable by 100 but not 400 is not a leapyear, so if you where born on Febuary 29th you could go seven years without a Birthday. Which you would excperience roughly every 25 years old you where.
