Beautiful twins in California might have been born just 15 minutes apart, but they were born in different years.

Alfredo Antonio Trujillo was delivered at 11:45pm on 31st December 2021 weighing 6 pounds, 1 ounce. He was soon followed by his twin sister, Aylin Yolanda Trujillo, who arrived at 12am on 1st January 2022 weighing 5 pounds, 14 ounces.

Aylin was the first baby to be born this year at Natividad Medical Center and in Monterey County, the hospital said in a statement.

"What makes their birth so rare is that they were born on different days, months and years," the hospital said.

The chance of twins' being born in different years is estimated to be 1 in 2 million.

Congratulations!
