National & International Days on October 31

Here’s a look at the many themes and observances that make October 31 a day of both celebration and reflection.

Books For Treats Day

Books For Treats Day encourages giving children books instead of candy on Halloween, turning a night of sweets into a celebration of reading. The idea began in 2001 when author and librarian Rebecca Morgan from San Jose, California, started handing out books to trick-or-treaters. She wanted to shift the focus from sugar to stories, offering something that could spark imagination and last far beyond the holiday. Morgan later founded the non-profit Books for Treats to expand the movement across the United States and Canada, helping thousands of communities share the joy of reading each Halloween.

Girl Scout Founder’s Day

Girl Scout Founder’s Day honors Juliette Gordon Low, the woman who introduced the Girl Scout movement to the United States. Inspired by the British Boy Scouts and Girl Guides, she aimed to give girls opportunities to learn leadership, practical skills, and independence at a time when such programs were rare for them. Low founded the first Girl Scout troop in Savannah, Georgia, in 1912, beginning a movement that grew into one of the largest organizations for girls in the world. Her birthday was officially designated as Girl Scout Founder’s Day in 1920 to recognize her lasting impact on generations of young women.

Halloween

Halloween is a day known for costumes, trick-or-treating, and spooky celebrations. Halloween is rooted in ancient traditions marking the end of the harvest and the coming of winter. Today, it’s one of the most widely celebrated holidays in many countries, filled with fun, creativity, and a dash of fright.

Hug A Sheep Day

Hug A Sheep Day* (Last Saturday of October) was created by “The Crazy Sheep Lady” of Equinox Farm in memory of her first rescued sheep, Punkin, and became an official observance in 2015. The day teaches appreciation for sheep as gentle, intelligent animals that provide wool and companionship. It encourages kindness toward farm animals and awareness of how they are cared for. Even though the name sounds playful, the message is serious—respect animals’ comfort, support sanctuaries, and understand that not all sheep enjoy close contact.

Lutefisk Day

Lutefisk Day honors one of Scandinavia’s oldest Christmas food traditions. The dish, called lutefisk, is made from dried whitefish—usually cod—that is soaked in water and then in a lye solution before being rinsed and cooked. This process gives the fish its soft, jelly-like texture and distinctive flavor. The custom began in the Middle Ages, when people preserved fish by drying it and ate it during fasting periods before Christmas. Over time, lutefisk became a holiday specialty across Norway, Sweden, and Finland, symbolizing both history and regional identity.

Muddy Dog Day

Muddy Dog Day* (Last Saturday of October) was founded by Jo Milnes, owner of the UK company Distinctive Pets, to lift people’s spirits after the COVID-19 lockdowns. The day celebrates dogs’ natural love for mud and puddles. It encourages pet owners to let their dogs enjoy being messy and adventurous instead of worrying about keeping them spotless.

National Caramel Apple Day

National Caramel Apple Day celebrates the beloved fall treat made by coating fresh apples in warm, melted caramel. This sweet combination likely began in the 1950s when Dan Walker, an employee at Kraft Foods, experimented with leftover Halloween caramels and created the first caramel-covered apple. The idea quickly caught on, and by 1960, Vito Raimondi patented a machine that allowed caramel apples to be produced on a larger scale. The day honors this happy accident that turned into a timeless autumn favorite.

National Doorbell Day

National Doorbell Day was created in 2017 by NuTone, a U.S. company known for its home products, to recognize the invention and importance of the doorbell. The observance also honors J. Ralph Corbett, who transformed the simple house buzzer into a pleasant-sounding door chime during the Great Depression.

National Increase Your Psychic Powers Day

National Increase Your Psychic Powers Day encourages individuals to explore and develop their intuitive abilities. The day invites people to learn more about extrasensory perception, such as telepathy, clairvoyance, or gut instincts, with the idea that everyone has some level of untapped psychic potential.

🔮 This observance is closely related to Psychic Day, which takes place on the first Sunday in August and shares a similar focus on curiosity, self-discovery, and exploring the unseen.

National Knock Knock Joke Day

National Knock Knock Joke Day celebrates one of the simplest and most recognizable forms of humor. These playful jokes, built around the “Knock, knock—Who’s there?” format, rely on wordplay and timing to make people laugh. Their roots go back to the early 1900s, when similar “Do you know?” jokes were popular, and by the 1930s, the modern version had become a widespread parlor game.

National Magic Day

National Magic Day commemorates the legendary magician Harry Houdini, who passed away on October 31, 1926. Houdini was known for his escape acts and showmanship, and his legacy continues to influence modern-day magic. National Magic Day honors both Houdini’s life and the art of magic itself.

National Pitbull Awareness Day

National Pitbull Awareness Day* (Last Saturday of October) was founded in 2007 by Bless The Bullys, a Tennessee-based rescue and education group, to challenge misconceptions about pit bull-type dogs. The observance promotes education, advocacy, and compassion by encouraging people to see pit bulls as loving and loyal companions rather than dangerous animals. It also raises awareness of breed-specific legislation (BSL) and the difficulties many pit bulls face in shelters. The broader goal of the day—and the entire Pitbull Awareness Month—is to inspire fair treatment, responsible ownership, and understanding for all bully breeds.

National Trick or Treat Day

National Trick or Treat Day* (Last Saturday in October) was created in 2019 by the Halloween & Costume Association to make Halloween celebrations safer and more convenient for families. The idea came from a proposal to move Halloween to the last Saturday in October, but instead, this new day was introduced to give everyone a chance to enjoy costumes, candy, and community fun without weekday conflicts. It encourages neighborhoods to host family-friendly events and helps children experience the excitement of trick-or-treating in a more relaxed and safer setting.

World Cities Day

World Cities Day was created by the United Nations in 2013 to remind people that cities are where most of the world now lives and where many future challenges will be solved. The day encourages everyone to think about what makes a city a good place to live—clean air, safe streets, affordable homes, and strong communities. It raises awareness of how thoughtful planning and care for the environment can make cities more inclusive, sustainable, and enjoyable for everyone.

World Savings Day

World Savings Day, also called World Thrift Day, was created in 1924 during the First International Savings Bank Congress in Milan, Italy. The idea came from Professor Filippo Ravizza, who wanted to remind people that saving money helps build stability and independence. The observance began after World War I, when many people had lost faith in banks, and it encouraged them to trust financial institutions again. Today, the day continues to spread the message that saving even small amounts can make a big difference for a person’s future and for the economy as a whole.
