They might have only been born 30 minutes apart but that half hour difference meant newborn twins Joslyn and Jaxon entered the world in different decades.
Parents Dawn Gilliam and Jason Tello of Indiana, welcomed baby Joslyn Grace Guilen Tello at 11:37pm on December 31, 2019 at Ascension St. Vincent Carmel hospital. Her twin brother, Jaxon DeWayne Mills Tello, was born at 12:07am on January 1, 2020.
"We're still in shock," Ms Gilliam told RTV6 of her babies' very unique birthdays.
While the twins weren't due until 19 February, a lack of movement resulted in the mum visiting hospital on New Year's Eve.
And it was a NYE to remember.
Almost two months early, Joslyn weighed just four pounds and 11 ounces, (2.1k kg) while her brother tipped the scales at four pounds and four ounces (1.9 kg).
"We've known for a while that she was going to be born first," Ms Gillam said. "She's been in position for most of the pregnancy."
Little Jaxon, however was breech. "So, it took a while for him to come."
But his fashionably late entrance meant Jaxon was the first baby born in the hospital for 2020
Dad, Mr Trello, who said he was "still kind of overwhelmed," admitted that the couple had talked about how great it would be for the twins to have different birthdays. But they certainly didn't predict they'd be born in different years.
"That was definitely interesting for us for sure. We're still kind of speechless still," he said.
But along with their special birthdays, Ms Gilliam, who already has two sons aged 10 and five says she's still trying to get her head around having twins.
"I guess it doesn't click that, 'Wow! We had two babies ... there's actually two,'" she said.
Currently in the NICU on feeding tubes both babies are otherwise healthy and doing well.
