The holiday is now celebrated in over 30 countries worldwide. National Nude Day came into being when former-rugby-player-turned-television-presenter Marc Ellis dared viewers to streak in front of New Zealand’s former prime minister, Helen Clark, some time at the beginning of the 21st century. The holiday started in New Zealand, and from there it spread to other Western countries. There is an entire movement devoted to this concept, known as naturism or nudism (although the two slightly differ). Many perceive this as a perverted notion, but the day celebrates freedom and the aesthetics of the human body. As the name suggests, people remove all articles of clothing on this holiday.
National Nude Day is celebrated all around the world on July 14.
