There are only about 5 million people in the whole world who were born on February 29, with the odds of being born on Leap Day standing at about 1-in-1,461. Several famous people—including actress and singer Dinah Shore (born 1916), motivational speaker Tony Robbins (born 1960) and hip-hop artist Ja Rule (born 1976)—are leaplings. Leaplings technically only get to celebrate their birthdays once every four years, but they do get to be part of an elite group.
