Happy Leap Day! Since it comes just once every four years, events that happen on February 29 are somewhat rare. Check out these eight events that are extra memorable thanks to their timing.

1. HATTIE MCDANIEL WON AN ACADEMY AWARD.

Actress Hattie McDaniel took home a Supporting Actress Oscar at the 1940 Academy Awards for her role as Mammy in Gone with the Wind. The win made her the first African American to receive the award.

2. BUDDY HOLLY'S LOST GLASSES WERE FOUND.

The singer's famous glasses disappeared for more than two decades after he died in a plane crash near Clear Lake, Iowa, in 1959. Holly’s trademark frames, along with the Big Bopper’s watch, were thrown clear of the plane wreckage. The items remained buried in the snow until the spring thaw, when they were turned over to the County Sheriff’s office and filed away in a sealed manila envelope. The envelope was rediscovered in 1980 by County Sheriff Jerry Allen, who came across it while looking for old court records. The discovery was announced on February 29, 1980. The glasses were returned to Holly’s widow, Maria Elena.

3. THE HENRIKSENS WERE BORN. (ALL OF THEM.)

Leif-Martin Henriksen

On February 29, 1960, Heidi Henriksen was born. Her brother, Olav, joined the family exactly four years later. And in 1968, to the day, Leif-Martin Henriksen entered the world. The Norwegian siblings held the Guinness record for most babies born on a Leap Day until 2012, when the Estes family from Utah tied them: Xavier Estes was born on February 29, 2004; Remington Estes in 2008; and Jade Estes in 2012.

4. DAVY JONES DIED.

In 2012, the Monkee passed away after suffering a heart attack. He was just 66, leaving many fans in shock at his unexpected death.

5. HANK AARON BECOMES THE HIGHEST-PAID MAJOR LEAGUE BASEBALL PLAYER.

A $200,000-a-year contract might seem like peanuts for a MLB player today, but by 1972 standards, it was a big deal. So big, in fact, that the three-year contract Aaron inked to play for the Atlanta Braves made him the highest paid baseball player in the league.

6. POPE JOHN PAUL II WAS NEARLY KILLED.

Back when he was just 24-year-old Karol Wojtyla, Pope John Paul II was walking home when a German army truck hit him and left him on the road for dead. The driver of a lumber truck picked him up and took him to the hospital, where Wojtyla remained unconscious for nine hours. It’s said that the incident inspired him to switch to a spiritual career path.

7. FAMILY CIRCUS DEBUTED.

On February 29, 1960, Bil Keane’s long-running comic strip debuted as The Family Circle. Inspired by Keane’s own wife and children, Family Circus is now drawn by Keane’s youngest son, Jeff—the inspiration for “Jeffy” in the comic strip.

8. THE FIRST WARRANTS WERE ISSUED IN THE SALEM WITCH TRIALS.

Salem residents Sarah Good, Sarah Osborne, and Tituba were accused of witchcraft on February 29, 1692. After refusing to confess, Good was hanged and Osborne died in prison; Tituba, a slave, admitted to her supposed crimes and was released from jail a year later.
