Every four years, February gets an extra day. At the city's marriage bureau Monday, couples lined up to say they got married on Leap Day. Our Manhattan reporter Michael Scotto has the story.

Amada Anderson and Damon Sugameli got engaged this past summer and didn't initially want to get married until later this year.

But when they realized a leap day was approaching, they, well, leaped at the chance to tie the knot on February 29.

"We basically said we want leap day," Anderson said. "And we were talking to our parents and they said it's too soon to get people to fly and it's too cold.

"And it's a Monday," Sugameli added.

"So we were like, we still want the date," Anderson said.

Part of the reason is they're a bit obsessed with time: The time-travel television show "Quantum Leap" brought them together.

When they have a bigger, more formal wedding later this year, time travel will be its theme.

Anderson and Sugameli were hardly the only couple looking to say 'I do" on a day that comes only every four years.

The city clerk's office married 266 couples, compared with 171 last Monday.

"Taking the leap on leap day -- It seemed right," said one of Monday's grooms, Joel Lowden.

Why do we have leap years? Jana Grcevich of the Museum of Natural History says the extra day is needed because the earth takes a bit longer than 365 days to travel once around the sun.

"It's actually 365 days and six more hours," Grcevich said. "And so, over the course of four years, you build up four times six hours, which is a whole day, and so we have to account for that extra day. 

That extra day isn't an exciting one everywhere in the world. In Greece, it's considered bad luck to get married on leap day.

But in New York, couples like Gregory and David Maro were deciding which day they'd use as their anniversary in non-leap years, February 28, or March 1? They plan to have a big celebration every four years.

"The next leap day is probably when we'll be able to afford the next big wedding," Gregory Maro said.

That would be in 2020. When many of Monday's leap-year newlyweds plan to say they're celebrating their "first anniversary."
