It's rare enough for twins to have different birthdays. But thanks to six timely deliveries flanking midnight Saturday, three sets of twins will grow up with different birth years.

In Minneapolis - one of the twin cities - Beckett Humenny was born 6:40 p.m. Dec. 31, 2011, followed by his sister, Freya, at 12:26 a.m. Jan. 1, 2012. In Buffalo, N.Y., Ronan Rosputni was born at 11:37 p.m., just 33 minutes before his brother, Rory, arrived at 12:10 a.m. (The Rosputni twins are shown in the photo above.) And in Tampa, Fla.,  Jenna and Leah Bear arrived at 11:59 p.m. and 12:00 a.m., respectively.

"It's a great way to end the previous year and start the new year," Blake Bear, now a father of three, told the Tampa Bay Times.

The six babies are healthy, ranging in weight from Beckett's 4 pounds 11 ounces (he and Freya were due in February, according to WCCO Minnesota) to Rory's nearly seven pounds.

Rory and Ronan's mom Brighid Rosputni , who attended her sister's wedding earlier on Saturday, said the timing her twins' births was "like a dream."

"They have completely different birth dates and years," she told The Buffalo News. "I don't know if it's ever happened. I'll have to do some research. I'll have to Google it."

The timing means the twins won't share a birthday, but they will share a great story.

"It's unique," Kathy Bean, a charge nurse, told The Buffalo News. "They definitely will have a story for the rest of their lives."
