Extraterrestrial Culture Day

Extraterrestrial Culture Day is one of the most original and unusual holidays in the world. This day celebrates alien culture—or, more accurately, how we imagine it. With so little truly known about extraterrestrials, you’re free to let your imagination run wild in how you mark the occasion.

History

Extraterrestrial Culture Day was first celebrated in the United States in 2003. Initially called Alien Day, it was later renamed to give it a more specific and intriguing title. The holiday has become popular not only in the U.S. but also in many other English-speaking countries.
