One of the girls was born at 11.59pm on Dec 31, and the other a minute after midnight on Jan 1, an official told AFP at a hospital in the coastal town of Split, where the babies were born.
“It is really an unusual situation,” head of the hospital’s perinatology department Damir Roje told local media.
He added that although he had seen twins born over different days before, it was the first time in his professional career that he had seen twin babies born over different years.
The tiny difference means the family will celebrate one of the girls’ birthdays on New Year’s Eve and the other one on New Year’s Day, he said.
