Age is just a number, especially when you’re 47 going on 12.
Nora Whalen and her identical twin sister, Ruth Whalen Crockett, were born on Feb. 29, 1976. That would make them now 48, but because Leap Day comes only once every four years, they’ve only had 12th true birthdays — including the one they celebrated Thursday night in north Minneapolis at a throwback party with several dozen family members and friends.
To celebrate the twins turning 12 again, well-wishers packed La Doña Cervecería for a evening that culminated with circa 1988 karaoke to relive the first time the sisters were 12. Belinda Carlisle, George Michael and Mr. Big graced the playlist, and this mostly Gen X crowd, along with their kids, belted out tributes to their favorite leaplings.

What’s it like being born on a day that is as rare as the Olympics or a presidential election?
“It’s the year I realize the people around me are math-challenged,” Nora said, noting that they can’t seem to divide or multiply easily in their heads by four. But it’s special, too. “Every four years I hear from people I haven’t heard from in four years.”
This Leap Day birthday was even more special because Nora got to party with her twin, something they haven’t done since they were 16 (or 4, depending how you’re counting). Ruth, who lives in Lowell, Mass., flew in to Minneapolis Thursday to join her sister for the festivities.
The crowd sang happy birthday to the sisters. And the twins, clad in matching Dickies pinstripe overalls, returned the favor with a gutsy rendering of “One Moment in Time,” which Whitney Houston crooned at the 1988 Summer Olympics in Seoul.

The world is home to about 5 million people who were born on Leap Day. The odds of having a Feb. 29 birthday are already slim, but they’re even rarer because obstetricians are scheduling fewer cesarean deliveries on that date, according to the polling aggregation site FiveThirtyEight. Many parents don’t want to deliver on Leap Day, afraid of relegating their children to birthdays that only return every four years.
