How Common Is Your Birthday?

My birthday isn’t common. It’s popular.

A friend posted an interesting data table on my Facebook wall yesterday, which was my birthday. The data listed each day of the year with a ranking for how many babies were born on each date from 1973 to 1999. Some interesting trends are evident in the data.

You can look up exactly how common your birthday is at this link, where they also find it necessary to tell us, without caveat, that February 29 is the least common of all.

Interesting how births fall in the 5-6 days surrounding Christmas. Willpower, I guess.
