Is it possible that Oct. 5 is the most popular birthday? I mean significantly more common than any other date? By how much? (I have anecdotal data about this question, but I’d rather go with stats). any help? ---

I always heard that whatever day falls 9 months from New Year’s Eve is the most common Birthday. October 5th is pretty darn close. ---

It’s my Mom’s B-day, but I had never heard that before. ---

You can get statistics in any municipal Hall of recordsm it’s public data. ---

Oct 5 is my brother’s birthday as well. Go ahead and add him to your list. ---

I have no idea how reliable this is (an “in depth database query” of what database, exactly?), but here’s a [link to a page](http://www.anybirthday.com/report.htm) which reports that October 5 is, indeed, the most common birthday (presumably in the United States). It also makes the New Year’s Eve connection. ---

Both my dad and his older sister were born on Oct. 5. I had never heard about it being the most popular, though. ---

Off the top of my head I can think of 9 people I know who were born on Oct. 5. I can think of 7 more who were born within days of that. My parents must have had a thing for winter lovin’: I was born on Halloween, but I was due on October 17th. My older brother was born on the 5th, my younger brother on Oct.10, and my sister on Oct. 14th. :rolleyes: No, not all in the same year. ---

According to most of the natality figures I could dig up on the web, there are more babies born in August and September than October. September usually has a slightly higher birth rate and August has more total births because it has 31 days. I doubt if anyone keeps track of the most common birthday nationwide, because no one compiles it. ---

According to [Anybirthday.com](http://Anybirthday.com), the 10/5 is indeed the most common Birthday with 12,576 people being born each year on the 5th of October. The connection to New Years is also mentioned on this site. What is strange is that according to Anybirthday, May 22nd is the least common Birthday, with an average of 10,259 persons born each year. Perhaps the heat of August is not conducive to conception. I can imagine many a drunken encounter on New Years Eve where the condom is blown up like a balloon, and thrown aside, “Woohoo!!! Happy New Year’s, let’s make a baby!!! What’s your name again?” ---

You’d think there’d be a spike of births around Nov. 14th (I know some, including a pair of twins) since that’s 9 months after Valentines Day. ---

It’s quite possible, too, that there isn’t any particular connection to conception dates, but that it’s just a fluke. Some day has to have the most births, after all.
