Twins but with separate birthdays.
In an unusual twist of time, for just fifteen minutes, a pair of twins was born in two different years.
It happened in California where a woman, Fatima Madrigal, first gave birth to Alfredo at 11.45 pm local time on New Year's Eve, while Aylin arrived fifteen minutes later, born at the stroke of midnight.
"It's crazy - said the mother - to have twins with different birthdays".
Alfredo and Aylin have three brothers, two girls and a boy.
According to the Centers for Disease Control and Prevention (CDC), the federal agency that deals with public health, there are about 120,000 twin births in the United States each year, or 3% of all births.
