Happy February 29! Why is a Leap Year special anyway? Read on to find out.

Many people think of a year as 365 days. It actually takes 365 and 1/4 days for the earth to revolve around the sun. That equals 6 hours each year, which adds up to this extra day in February every 4 years.

Those born in Leap years are called leapers or leaplings. To celebrate birthdays in years where there is no February 29, most states dictate their birthday as being March 1.

Is it bad luck luck to get married on February 29? Americans don't seem to think so. On the last February 29, in 2008, the number of marriages more than doubled the daily average in New York City. An anniversary every four years! Perfect for the cheapskates!

The chances of being born on a Leap day are 1 in 1,500. Close to 10,000 U.S. babies will be born today.

Are you superstitous on days like this? How does a Leap Year affect you?
