a former co-worker born on Feb 29th, the odds of a such a birthday is about 1460 to 1. He is the only person I know with such a birthday.
In that office of 8 people, 6 of us had birthdays within a 14 day range, and the other two were in December, 2 days apart.
samarm, that’s actually a great bar bet. Wikipedia calls it the birthday paradox: namely, that in a room with 23 people, the odds are 50-50 that two of them share the same birthday (month and day, not year). With 57 people in the room, the odds go up to about 99% certain that two people share a birthday.
And me, I was born November 17, 1971. No famous birthdays … not even any famous death days.
James Dean: Feb 8th, 1931
Me: Feb 8th, 1981
Both junior college transfers to UCLA, as well.

As for non-famous people, I share my birthday with one of my older nieces, as well as one of my sister’s friends and the mother of another friend.
Rebecca De Mornay, Tony MacAlpine–guitarist, Chris Hadfield–RCAF/astronaut, STS 74, sk: 99, Michael Jackson, John McCain, Ingrid Bergman and Henry V, king of England.
Pretty bad ass company.

ETA – and Drew Curtis 
Juan Carlos I of Spain, Marilyn Manson, Hayao Miyazaki, Kyle Calder, January Jones and Rick Campanelli, to name but a few.
I thought that the OP was referring to the very same day (i.e. date and year), in which case no, but I was born the day Hosni Mubarak became president of Egypt.
Actually, Wikipedia tells us that there was someone born on my birthdate: the mellifluously named Minnesota Twin, Boof Bonser.
Me too, **Suburban Twin!**I’m younger than the Queen Mother by quite a lot (and less dead) and a bit younger than Obama.
Only one I can think of off the top of my head is John Glenn.

And in another two years, I’ll make him proud. 
As to other famous March to the 11th-ers, my favorites are Thora Birch, Bobby McFerrin and (hehe) Lawrence Welk. I’m sure there’s others, but I can’t remember them from when IMDb shows them daily.
