The most common birthday is September 9th.
The concentration of births around September 9th isn't random; it's likely due to a confluence of factors related to conception patterns. Nine months prior to September is December, a time when many couples may be more likely to conceive due to holidays and associated time off work, leading to more relaxed and intimate settings. This isn't a hard science; it's more about examining statistically higher occurrences.
The distribution of birthdays throughout the year isn't uniform. There are definitely less common birthdays, usually around holidays like Christmas or New Year’s Day. This is speculated to be due to doctors scheduling fewer deliveries on those days, if possible.
In conclusion, while every birthday is special, September 9th holds the statistical title of the most common birthday, likely linked to December conception patterns.
