Commemorates the day in 1974 when Gerald Ford became President without ever having been elected as either vice president or president. Ford had become vice president after Spiro Agnew resigned due to a kickback scandal. When Nixon later resigned amid the Watergate scandal, Ford found himself occupying the Oval Office. This was the first time the VP had become president under these terms.

7. August 10: S'Mores Day

The original recipe, published in Scout leader Loretta Scott Crew's 1927 Tramping and Trailing with the Girl Scouts, called these campfire treats Some Mores.

8. August 12: Vinyl Record Day

First declared such in 2002, Vinyl Record Day is held on the anniversary of when Thomas Edison invented the phonograph in 1877.

9. August 15: Chauvin Day

If you're worried that this is a day to celebrate chauvinists—you're actually kind of right. But don't worry. On the anniversary of Napoleon Bonaparte's birthday we celebrate the interesting etymological history of the word "chauvinism," which comes from a man named Nicholas Chauvin, who so idealized Napoleon that he became internationally mocked for his blind loyalty to a cause. From there the term became associated with any misguided or ill-intentioned adherence to a particular cause, and finally, the discriminatory mindset it refers to today.

10. August 16: National Roller Coaster Day

This thrilling holiday is celebrated on the anniversary of the first U.S. patent awarded for a roller coaster, Richard Knudsen and J.G. Taylor's 1878 wooden design. The first roller coaster wouldn't be built, however, for another couple years by someone else entirely.

A day to soothe the bruised egos of poets mocked just three days prior on August 18's Bad Poetry Day.

13. August 25: Founders' Day

Head to your nearest park on the anniversary of the 1916 founding of the National Park Service.

14. August 26: Women's Equality Day
