August is known for having the most birthdays during the year. However, did you know September 9th is the most popular birthday in the United States? 

September 9th may have a higher number of births compared to other dates. The average number of births per year on this date is 12,301. This author’s sister and grandmother were both September 9th birthdays. Do you know any September 9th birthdays? 

What makes this such a popular day? Some researchers suggest that there might be a higher number of conceptions during the winter months due to factors like colder weather, which can lead to increased indoor activities and close contact. This could potentially result in more births around the late summer and early fall months, including September.

As we get ready for birthdays, what are some of your birthday tips? What do you like to do for you or your family? We have some ideas on where you can have your next party. This list has choices all over town and for a variety of ages.
