If your birthday is on September 26, we have some bad news for you – your ‘special day’ isn’t that exceptional.
New data from the Office for National Statistics (ONS) has revealed the most common days to be born on in the UK.
The stats show that between 1995 and 2025, September 26 was the most common day to be born on.
In fact, the 10 most common birthdays all fall in September – 26, 25, 27, 23, 30, 19, 22, 24, 18, 29.
With a bit of quick maths, you’ll work out that this shows that more babies are conceived in the weeks around Christmas than at any other time of the year.
In contrast, the Christmas period itself is the least common time for a birthday.
Boxing Day (December 26) is the day you’re least likely to have a birthday, ahead of Christmas Day (December 25), and New Year’s Day (January 1).
So, how common is your birthday? Use our interactive tool below to find out.
The ONS released its birth registration data for 2025 this week, which the Daily Mail compiled with the previous 30 years of data to uncover the most common birthdays.
To try the tool yourself, simply click on the rectangle that represents your birthday, or select your birthday from the drop down.
You’ll then be told how your birthday ranks, and the average number of babies born on that day each year.
September 26 tops the list as the most common birthday, with an average of 1,927 babies born on that day every year.
Celebrities with this birthday include Serena Williams, Chloe Burrows, and the late Olivia Newton-John.
According to Jay Zagorsky, a senior lecturer at Boston University, September birthdays being the most common ‘makes sense’.
In an article for The Conversation, he explained: ‘Fall [autumn] birthdays make sense since many babies are conceived during the colder winter months.
‘Conception is tied to shorter days and lower outside temperatures.’

At the other end of the list, just 1,293 babies are born on December 26 every year on average.
This doesn’t necessarily imply that less babies are conceived nine months before then, in March.
Instead, this is largely a reflection on the healthcare system, according to Mr Zagorsky.
‘One reason why these days have so few births is almost no cesarean births are scheduled by doctors to happen on public holidays or weekends,’ he explained.
‘And even in the case of vaginal births, doctors can induce labor, which helps control when babies are born.
‘Inductions also typically don’t happen when doctors want to be out of the office celebrating the holidays with family and friends.’
Another uncommon birthday in the UK is 1 April, with just 1,686 babies born on this date every year on average.
‘While that date is not a national holiday, mothers might avoid giving birth on April Fools’ Day for fear of their children being taunted or bullied,’ Mr Zagorsky added.
