A comprehensive new study has debunked the popular “Monday’s Child” nursery rhyme, finding no evidence that the day of birth influences a child’s personality, appearance, or future success. Researchers at the University of York analyzed data from over 1,100 twin families tracked from ages five to eighteen, conclusively showing that Wednesday’s children are no more “full of woe” than Monday’s children are “fair of face.”
The study, published in the Journal of Personality, examined whether the centuries-old nursery rhyme held any predictive power by analyzing various potential effects. Researchers investigated whether children might develop traits to match the rhyme through self-fulfilling prophecy, confirmation bias, or parental influence.
“In an age where parents are increasingly concerned about the messages children encounter, our findings offer reassurance: nursery rhymes like ‘Monday’s Child’ are simply harmless fun,” said Professor Sophie von Stumm, senior author from the University of York’s Department of Education.
The research team utilized data from the Environmental Risk (E-Risk) Longitudinal Twin Study, which has tracked over 1,100 twin families from England and Wales since 1998. This robust sample allowed researchers to control for genetic factors while isolating environmental influences.
Despite plausible theories about how the rhyme might subtly shape development, the study found no connection between birth day and life outcomes. Instead, researchers confirmed that socioeconomic background, sex, and birth weight are far stronger predictors of a child’s development than folklore suggests.
Lead author Dr. Emily Wood commented on why such beliefs remain popular: “People like to have a simple explanation for their personality traits, a phenomenon exemplified by the long-standing popularity of astrology. Our study was a bit of fun, but it also reiterates that your family background and other environmental factors have a much greater influence on your life’s path.”

The “Monday’s Child” rhyme, which dates back to at least the early 19th century, assigns different characteristics to children born on each day of the week. According to the traditional verse, Monday’s children are “fair of face,” Tuesday’s are “full of grace,” Wednesday’s are “full of woe,” Thursday’s have “far to go,” Friday’s are “loving and giving,” Saturday’s “work hard for a living,” while Sunday’s children are “bonny and blithe, good and gay.”
The researchers note that while this nursery rhyme remains well-known in the UK, it doesn’t hold the same cultural influence as beliefs like the Zodiac years in China, where previous studies have shown such prophecies can significantly shape a child’s life.
Despite debunking the rhyme’s predictive claims, Professor von Stumm emphasizes that nursery rhymes still offer important benefits for child development: “We know these rhymes are rich in alliteration and vocabulary which has been shown to boost language and literacy, so parents should absolutely continue to share them.”
The study provides welcome reassurance to parents who might worry about outdated messages in traditional nursery rhymes. By separating folklore from science, researchers have confirmed that a child’s development is influenced by substantial environmental and genetic factors rather than something as arbitrary as their day of birth.
For parents of “Wednesday’s children” who might have harbored concerns about predestined “woe,” the message is clear – the day of the week a child is born has no bearing on their personality or future. The research highlights that while nursery rhymes remain valuable for language development through their rich alliteration and vocabulary, their predictive claims about personality are nothing more than harmless fun.
