September 9th is the most common birthday of the year … or is it?

I was talking to my friend who runs the website What Does My Birthday Mean and she told me something fascinating …. did you know that more people celebrate their birthday’s on September 9th than any other day of the year in the US? Well, that is, according to who you ask. There is another report that says it’s September 16th.

In 2006 researchers at Harvard University examined births between 1973 and 1999, and found that the most common birth date for those years was Sept. 16. But another researcher compiled data on all births from 1994 to 2014 from the Health Statistics and the Social Security Administration, and he found the most common date of birth is September 9th.

No matter which data set you look at, September is a popular time to give birth. The newer data shows that 9 of the top 10 days to give birth fall between Sept. 9 and Sept. 20. Given that pregnancies last an average of about 38 weeks, this means many people are conceiving in December, around the holidays. Yep, that means your parents are celebrating Christmas in the sack!

On the other hand, winter months like December, January, and February are among the least common times for babies to be born. In fact, Dec. 25 and Jan. 1 are the least popular dates in both data sets. July 4 is also a very uncommon birthday. This likely suggests parents are planning their children’s births, Stiles notes on his site, or that doctors take vacations and try to schedule births on non-holidays.

Those born on September 9th or even those born on September 16th are Virgos, the most workaholic sign out of all the signs of the zodiac. If you want to know about your horoscope don’t forget to check out your free daily reading.
