An American mother has sparked discussion online after revealing that she has named all seven of her children after the days of the week, with their unusual names ranging from Sunday to Saturday.

Britney Donley, from Michigan, came up with the idea when she welcomed her first child at the age of 20. Having not settled on a name before giving birth, she turned to a nurse for inspiration by asking what day it was.

When the nurse told her it was Sunday, she decided that would be the name of her daughter, unknowingly starting a tradition that would eventually extend across all seven days of the week.

Six children later, Britney had completed the set, naming her children Sunday, Monday, Tuesday, Wednesday, Thursday, Friday and Saturday.

Interestingly, the names were not simply chosen at random, as Britney revealed that each of her children was actually born on the day they were named after.

Speaking to TODAY.com, she said: “I can’t make it up,” explaining just how perfectly the unusual naming tradition had worked out.

Her eldest daughter, Sunday, has since graduated from high school and hopes to become a teacher, while her six siblings complete the rest of the weekly calendar.

The mother explained that she never intended for the names to become a talking point or attract attention from strangers, but they have certainly made an impression whenever the family are out together.

“When we’re out together and I call for Monday or Tuesday, people turn their heads,” she said.

However, there is a more personal reason behind Britney's decision to give her children names that follow the same theme.

Growing up in a family of eight children herself, she had always imagined having a large family of her own. She also wanted to make sure her children shared a strong bond with one another, particularly as they have different fathers.

For Britney, giving them names connected by the same theme was one way of creating something special that they could all share.

“I wanted them to be close. That has always been really important to me. And they are close. They do everything together.”

Although the names initially took some getting used to, particularly for her son Monday, who was not particularly fond of his name when he was younger, Britney says the children's attitudes have since changed.

She explained that Monday previously preferred using his surname at school and would rarely introduce himself by his first name.

However, after the family began sharing their lives online and receiving positive reactions from viewers, the children gradually became more comfortable with their unusual names.

“Now they love them,” Britney said. “People tell them how special they are.”

The mother has also revealed that she does not currently plan on having any more biological children, although she hopes to become a foster or adoptive parent in the future.

And if she does welcome any more children into her family, she already has another naming theme in mind, suggesting that she could move on from the days of the week to the months of the year.

The story has since prompted plenty of reactions online, with people sharing their thoughts on the unusual naming decision.

One person joked:

“This must’ve been inspired by the movie ‘What Happened to Monday’ lmaoo!”

Another was more interested in the coincidence behind the names, asking:

“I think the deeper question is were they born on the day they were named after!?”

A third person joked commenting:

“At this point she might start using the months too lool.”

While the names may not be everyone's cup of tea, Britney's story has certainly caught people's attention, particularly given the coincidence that all seven children arrived on the corresponding days of the week.
