It will make for an interesting story later in life when they get asked — as most twins do — “Which one of you is older?”

Samuel was born first, but his twin brother, Ronan, is officially older. You read that correctly. How could this happen? Daylight Saving Time.

Cape Cod Healthcare posted the interesting twist on its Facebook page after the twin boys were born at Cape Cod Hospital in Hyannis, Massachusetts.

The hospital said Samuel was born at 1:39 a.m. on Sunday, Nov. 6. By the time Ronan was born 31 minutes later, Daylight Saving Time had ended, and the time fell back an hour – that made Ronan’s official time of birth 1:10 a.m. So, on paper, Ronan is the older twin.

President and CEO of Cape Cod Healthcare, Michael K. Lauf, told ABC News that “the Peterson twins’ birth story was a remarkable occurrence.”

He added, “Our veteran maternity nurse, Deb Totten, said it was the first time she has seen it in more than 40 years of nursing.”

The boys’ parents, Emily and Seth Peterson, think it’s “kind of cool.”

“I said earlier that night that they were either going to be born on two different days or the time change was going to come into play,” Seth said.

Samuel and Ronan are healthy and have gone home, where they are hanging out with their big sister, 2-year-old Aubrey.
