2016 being a leap year, has 29 days in February. Every fourth year is a leap year, EXCLUDING century years such as 1800, 1900, 2100 and 2200 but INCLUDING every 4th century year such as 1600, 2000 and 2400.
Here is a rather short list of notable people born on February 29, who got to celebrate their real birthday every 4 years. One of the people listed below was born in 1896 so he got to celebrate his first birthday only in 1904. Anyway, he lived until 1995 so he did celebrate many birthdays.

Morarji Desai (Indian politician)-1896
Rukmini Devi Arundale (Indian dancer)-1904
Alf Gover (English cricket coach)-1908
Sean Abbott (Australian cricketer involved in the Phil Hughes tragedy)-1992
There are not as many names as you would expect. But this day comes only once in four years.
