🎂 Most Common Birthdays
⭐ Rarest Birthdays
💡 Did You Know?
September is the most popular birth month because babies are often conceived during the December holiday season!
Holiday birthdays are rare because fewer planned births (like C-sections) are scheduled when medical staff are off work.
Your "golden birthday" is when you turn the age of the day you were born (e.g., turning 25 on the 25th).
Why Are Some Birthdays More Common?
The September Peak
September consistently has the most common birthdays in the US. The reason? Count back nine months and you land right in the December holiday season. Research suggests that people are generally happier and spend more time together during holidays, leading to more conceptions.
Holiday Birthdays
Christmas, New Year's Day, and other major holidays are among the rarest birthdays. This is partly due to people planning around holidays and partly because scheduled births (like C-sections) don't typically happen when hospitals are minimally staffed during holidays.
Seasonal Patterns
Birth rates show clear seasonal patterns. Summer and early fall see more births, while late winter and early spring tend to have fewer. These patterns have been consistent across decades of data.
Cultural Factors
Some researchers believe that cultural factors play a role. For example, people may intentionally plan pregnancies to avoid having children with holiday birthdays, believing it could be less special to share a birthday with a major holiday.
Note: Birthday statistics vary by country and can be influenced by many factors including culture, climate, and social patterns. These findings are based primarily on US data.
