Extraterrestrial Culture Day is celebrated annually on the second Tuesday of February, with a focus on recognizing extraterrestrial cultures and humanity's relationship with the cosmos. This day encourages people to explore the mysteries of celestial civilizations and contemplate their place in the universe. It was founded by Daniel Foley and the New Mexico Legislature, inspired by the famous Roswell Incident, which has made Roswell, New Mexico, a hub for UFO-related activities. Typical customs include visiting Roswell to engage with its alien-themed attractions, such as the International UFO Museum and Research Center, and watching classic alien movies like "E.T. the Extra-Terrestrial" and "Close Encounters of the Third Kind." The celebration aims to honor all past, present, and future extraterrestrial travelers and strengthen ties between known and unknown citizens of the universe.
