29th February comes only once every 4 years, and 2012 is one of those years!
Fun facts: It takes the earth 365.24219 days to travel around the sun, and that's why we have an extra day every 4 years!

Why do we need a leap year?
Leap year began in order to align the earth’s rotation around the sun with our seasons. It takes approximately 365.2422 days for the earth to travel around the sun in one year. We know that a typical year has 365 days in it—but as you can see from the number 365.2422, a year is not exactly 365 days! So, in order to get “lined up”, almost every four years, we give one extra day to account for the additional time the earth takes to travel around the sun.
Thirty Days hath September poem
Thirty days hath September,
April, June and November;
February has twenty eight alone
All the rest have thirty-one
Except in Leap Year, that's the time
When February's Days are twenty-nine
April, June and November;
February has twenty eight alone
All the rest have thirty-one
Except in Leap Year, that's the time
When February's Days are twenty-nine
