If you ask Carter what his favorite part of his birthday is, it’s not the Spider-Man theme or even the presents that stand as tall as he is.
It's the date of his birthday.
“February 29!" exclaimed Carter.
He's a Leap Year baby, also called a "leapling." Carter turns four years old today and is celebrating well, his "second" birthday.
He is one of about 205,000 Americans born on February 29.
Leap day is once every four years so the probability of having a leap year birthday is small, about 1/1461, considering that's how many days are in a four year span.
Most leaplings celebrate on February 28th, which is what carter and his family did, but his mom, Danielle Oliver, has a little something extra planned for his special day.
"We will be taking him surprise cupcakes and balloons to school where the other years we wouldn't normally do that,” said Danielle.
Danielle is pregnant and expecting her next baby in April, but what if she had two leap year babies?
“I will stand on my head tomorrow if that's about to happen,” said Danielle with a laugh. She says that her baby is due on April 20th…tax day.
