May day! May day! We’ve got lots of May days! 

May 4: National Candied Orange Peel Day

There’s truly a “holiday” for everything if there’s a day recognizing candied orange peel. These boiled, sliced, and sugared bits of citrus are most commonly found in fruitcake and other winter desserts, so it’s a little perplexing why this day falls in early May.

May 5: National Hoagie Day

Hoagie, hero, sub, Dagwood—call a big, long sandwich with everything on it what you want, but the holidays is officially National Hoagie Day. The best way to celebrate is, of course, to eat a giant hoagie (or hero, sub, Dagwood…)

May 6: International Tuba Day

The first Friday in May is always International Tuba Day. Patented in 1835 in Germany, the tuba is a huge brass instrument that can weight as much as 50 pounds and provides the “bottom end” in marching bands and orchestras. The holiday was created in 1979 by a high school student named Joel Day. He was a tuba player in his Philadelphia high school marching band, and he felt like he and his fellow tuba players didn’t get enough respect.

May 16: Wear Purple for Peace Day

Are you in favor of world peace? Great! Show that you support that cause by wearing purple on this day, and acknowledge anybody else you see wearing purple. But what organizers really intended: If everyone on Earth wears purple at the same time, it creates a collective consciousness, which in turn will signal to extraterrestrials that humans are peaceful and welcoming.

May 23: Sally Ride Day

On May 26, 1951, Sally Ride was born in Los Angeles. A little more than 32 years later, she was onboard the second flight of the Space Shuttle Challenger and became the first American woman in space.
