Using Harvard University data, the graph shows September 16 as the most common birthday in the U.S., while December 25 and February 29 are the least common. The heat graph, while telling you how popular your birthday is, also successfully tracks trends in the data. Evidently, a large proportion of babies are born in September, with the top ten birthdays falling within the autumn month. Possibly confirming suspicions we have long held about conception trends, September is nine months after the holiday season.
