Famous birthdays: who shares your birthday?

Pick a day to see notable people born on it, plus events and births from the year you were born, pulled live from Wikipedia's "On this day" records.

How common is your birthday?

Birthdays aren't evenly spread. Analyses of US Social Security Administration birth data from 1994–2014 (published by FiveThirtyEight) found mid-September dates the most common, around nine months after the December holidays. The rarest were holidays themselves: 25 December, 1 January, 24 December, 4 July and 29 February, since scheduled inductions and caesareans are rarely booked on public holidays.

With about 8 billion people on Earth, roughly 22 million share any given birthday. Only a few hundred make it onto Wikipedia's list.
