Two sets of twins born as 2011 ticked over into 2012 will have found themselves in the unlikely situation of having birthdays in separate years.
The Daily Mail reports that in Buffalo, New York, young Ronan Rosputni was delivered at 11:37pm on December 31, 2011, while his younger brother Rory arrived at 12:10am on January 1, 2012.
Minnesota woman Stephanie Peterson had to wait a lot longer for her second baby with daughter Freya born at 12:26am on the first day of 2012, more than six hours after twin brother Beckett.
"When Freya was finally born the nurses had made confetti and threw confetti all over and everybody was clapping, so it was a party when she came," Ms Peterson told CBS news.
Mother of the New York twins, Brighid Rosputni, couldn't believe the unlikely birth.
"They have completely different birthdates and years, I don't know if it's ever happened. I'll have to do some research," she said.
