When two Arizona parents headed to the hospital to give birth to their twins, they weren’t expecting to leave with two babies born in separate years.

As 2017 got closer, Holly and Brandon Shay said they thought their twins could be born on New Year’s.

“It was a surprise. The timeline kept getting closer and closer and when we went to the hospital we didn't know that we were going to get admitted,” Brandon told InsideEdition.com.

Holly was admitted to Banner Thunder Medical Center in Glendale at about 5:30 p.m. Saturday at 37 weeks pregnant.

Everett Shay became Banner Health’s first baby born in 2017 when he arrived at 12:01 a.m., but his brother, Sawyer Shay, had been born 11 minutes prior at 11:50 p.m., just before the New Year hit.

“The babies were both almost born in 2016, but Everett was being stubborn and after losing suction a few times we were able to miraculously extract Everett as the clock officially struck midnight and the time in seconds was rounded to the nearest Minute for a 12:01 birth,” Brandon said.

Sawyer weighed in at 5 pounds, 5 ounces, while Everett was 4 pounds, 8 ounces, hospital officials said.

“Their birthdays are so special and now it is going to be shared by everyone to tell the story for years to come,” said Brandon. “Their personalities are really awesome and I think they are going to be best friends forever.”

The twins were one of four sets born in separate years this New Year, including twins in Georgia, Utah and California.
