SAND SPRINGS, Oklahoma (KOCO) — An Oklahoma woman is about to turn 100, but it’s really only her 25th birthday.

Mary Forsythe was born on Feb. 29, 1924 – Leap Day. Since leap years come around every four years, she will technically celebrate her 25th birthday this year.

The party got started a little early as the Sand Springs community gathered to celebrate Forsythe.

History.com says only about 5 million people worldwide have a Leap Day birthday and that the odds of being born on Leap Day stand at about 1-in-1,461.
