Leap Day birthdays: How to calculate age, list of celebrities, famous people born Feb. 29

Happy birthday, leaplings! As you know, there is no Feb. 29, 2025, 2024 was the most recent Leap Year, and the next Leap Day is not for another three years.

But … leaplings do something unique: They can calculate their age in in Leap Day years. Since Leap Year occurs once every four years — 2020, 2024 and 2028 is the next one, for example — this "Leap Day math" applies to people born Feb. 29. (Scroll down for a list of celebrities and notable people who were born Feb. 29.)

Those born on that day don't always get to celebrate their actual birthday — since that date occurs only every four years. But not to worry, someone born on Leap Day still gets to celebrate a birthday (see below).

For example, John Dunbar, executive editor of The Daytona Beach News-Journal, gets it: On Feb. 29, 2024, he turned “15, so I am still not old enough to drive,” he joked. “People always ask me what day do I celebrate my birthday on. When I was a kid, it was (February) the 28th because I wanted my birthday present. When I grew up I switched to March 1 because it seemed more honest."

Dunbar reflected about counting the days and, er, years until Feb. 29: "It's always a special day to have an actual birthday,” he said. “I used to have big blowout parties, but I'm pretty mellow about it these days."

How old would you be if you were born on Leap Day? We did the math for you.

How old are you technically if you were born on Leap Day? If you were born on Leap Day 1924, you would be 100 years old, or 25 in Leap Day years. On Feb. 28, 2025, or March 1, 2025, you would be 101 years old in real life and “still 25 in Leap Day years.”

The year must be evenly divisible by 4. If the year can be evenly divided by 100, it is not a leap year unless the year is also evenly divisible by 400, according to mathisfun.com. For example, 2000 and 2400 are leap years, but 1800, 1900, 2100, 2200, 2300 and 2500 are not.
