Luke and Hillary Gardner never have a problem remembering each other’s birthday. After all, the man and the woman were born on the day. And so was their son, 27 years later, this past December.
The odds of that happening are about one in 133,000, statisticians say. And that is a lot less likely than being hit by lightning sometime in your life, some of which is at about 12,000.
They were not directed at a joint birthday when their son Cade Lee Gardner was coined, said Luke Gardner, an assistant pastor in a Baptist church in the north-east of the Mississippi and a student at a nearby campus of New Orleans Baptist Theological Seminary.
“I had not even put it together, until we’re pregnant,” he said in a telephone interview Wednesday. “Then we realized, ‘Oh, wow!'”
With the help of a smartphone app, said he, his wife calculated end date of Dec. 15, three days before their shared birthday. Her midwife called it for Dec. 19.
So the few of Baldwyn, Mississippi, got in some exercise, to try to hurry the baby a bit. The night of Dec. 17, Gardner said: “we went walking” around the parking lot at First Baptist Church of Baldwyn, where Gardner is the scope of the pastor.
Or the exercise accelerated things, Cade was born at 10:01 pm, Dec. 18 — exactly 27 years after his parents on the birth date.
“Hillary is exactly six hours older than me,” Lucas Gardner said. She was born at 8:10 pm and her husband on 2:10 pm on Dec. 18, 1989.
They learned about their joint birthday before they started dating, while only a part of a group of friends who hung together.
“I saw it on a Facebook page first and asked,” Gardner said. “I couldn’t really believe it when I saw it. I had to confirm it with her.”
The chance of meeting someone born on the same day as you in 365, explained Tumulesh Solanky, chairman of the mathematics department of the University of New Orleans. He said that the chance of two people born on the same day and with a baby on their birthday is about 1/365 times 1/365.
“That comes out on .0000000751 — seven zeros, and then 751,” or about 7.5 million, he said, which equates to about one in 133,000. Statisticians note that this ignores factors such as leap years and the fact that the births are not evenly distributed over the whole year.
Gardner joked that if he and Hillary Gardner have more children, they may try for December.
“If we have more children, if we don’t get pregnant in March, we will have to wait until the following year,” he said.
