A heat graph, which corresponds the number of births on any given day to light and dark squares, effectively shows how American birthdays rate against each other.
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.
The least common birthdays fall at the beginning of January, at the end of November, and around Christmas time.
Interestingly however, December 30 is a more common birthday.
