There are a lot of people who share my birthday!

Did you ever wonder why you share your birthday with so many people - or so few people?

How common is your birthday? There's a chart that shows you.

There are days of the year that are more popular than others - while there are dates least common for birthdays.

This graph shows that September 16th is the most common day for birthdays, while February 29th is the least common. (No surprise there - it only occurs every four years.)
