Adult Autism Awareness Day
Adult Autism Awareness Day was founded in 2009 by the Association on Higher Education and Disability (AHEAD) to raise awareness of the experiences and challenges faced by adults on the autism spectrum. While originally focused on college students, the day has grown to promote understanding, accessibility, and inclusion in education, employment, and community life for all autistic adults.
Husband Appreciation Day
Husband Appreciation Day* (Third Saturday in April) encourages spouses to acknowledge the efforts, patience, and love that husbands offer daily. It’s a moment to say thank you and celebrate the men who help build strong families and relationships through their dedication.
International Amateur Radio Day
International Amateur Radio Day commemorates the founding of the International Amateur Radio Union (IARU) in 1925. Radio amateurs around the world mark the occasion by taking to the airwaves, highlighting their role in pioneering global communication and discovering shortwave propagation. The IARU was formed in Paris to protect amateur radio’s place on the electromagnetic spectrum.
International Day for Monuments and Sites
International Day for Monuments and Sites, also known as World Heritage Day, was established in 1982 by ICOMOS and officially adopted by UNESCO in 1983. Celebrated globally on April 18, it promotes awareness of cultural heritage’s diversity, significance, and vulnerability, while highlighting the importance of preserving historic sites through local and international cooperation.
International Jugglers Day
International Jugglers Day was established by the International Jugglers’ Association (IJA) in the mid-1980s. It celebrates the global juggling community. The IJA, founded in 1947, uses this day to promote the art and history of juggling, a skill with roots as far back as 2000 BCE. Events and workshops encourage enthusiasts to showcase their talents and connect with fellow jugglers worldwide.
🤹 Worth noting, there is also a separate World Juggling Day, observed on the Saturday closest to June 17, which was originally called National Juggling Day but was renamed in 1995 to reflect the IJA’s global reach.
National Animal Crackers Day
National Animal Crackers Day brings people back to their childhood memories and the many boxes of animal crackers shared with friends. The Stauffer Biscuit Company started making animal crackers in 1871, and the most popular brand, Barnum’s Animals, began in 1902 by the National Biscuit Company, now known as Nabisco, named after showman P.T. Barnum and sold in boxes designed to look like circus trains.
National Columnists’ Day
National Columnists’ Day was established by the National Society of Newspaper Columnists to honor columnists and their role in informing the public, shaping opinion, and holding power accountable. It also commemorates the death of Pulitzer Prize-winning war correspondent Ernie Pyle, who was killed in Okinawa on April 18, 1945. Columnists provide insight, spark debate, and offer personal perspectives on local and global events.
National Exercise Day
National Exercise Day was first observed in 2020 and created by Dr. Jeuse Bernard Saint-Fleur, who wanted to raise awareness about the fact that exercise can actually save lives. It promotes the benefits of movement are available to everyone regardless of age, fitness level, or resources, drawing attention to the gap between what decades of research shows and what most people actually do.
National Lineman Appreciation Day
National Lineman Appreciation Day honors the electrical lineworkers who maintain the power grid, often in dangerous conditions and extreme weather. The day was the brainchild of journeyman lineman Bill Bosch, who felt the public was largely unaware of what lineworkers do and pushed for congressional recognition. He proposed April 18 because his father, Cliff Bosch, also a lineman, passed away on that date. On April 10, 2013, US Senate Resolution 95 officially designated April 18 as National Lineman Appreciation Day, a move driven in large part by the massive response to Hurricane Sandy in 2012, when line crews across the country worked around the clock to restore power to millions of people.
National Piñata Day
National Piñata Day celebrates the colorful candy-filled containers used in celebrations around the world. Piñatas likely originated in China, traveled through Europe, and were adopted and transformed in Latin America. The observance was created in 2016 by Amy Watkins, an American artist and blogger who posted on her blog “Cozy Reverie” that she couldn’t believe a holiday dedicated to piñatas didn’t already exist. With the help of some friends, she turned the idea into an actual celebration.
National Poem in Your Pocket Day
National Poem in Your Pocket Day* (Date Varies During National Poetry Month) was started in New York City in 2002 and taken national by the Academy of American Poets in 2008. It encourages people to carry a poem with them and share it throughout the day. In 2016, the League of Canadian Poets extended the day to Canada as well.
National Record Store Day
National Record Store Day* (Third Saturday of April and again the day after Thanksgiving) was founded in 2007 by a coalition of independent record store owners. The first official celebration took place in 2008, with Metallica meeting fans at Rasputin Music in San Francisco. Since then, the event has grown into a global celebration of vinyl culture, featuring limited-edition releases, artist performances, and in-store events. The day highlights the unique role independent record stores play in preserving music culture, from rare vinyl and album art to fan communities and local music scenes.
National Velociraptor Awareness Day
National Velociraptor Awareness Day highlights the gap between the real animal and its Hollywood depiction, since the actual velociraptor was roughly the size of a turkey, weighed about 15 kilograms, and was covered in feathers — nothing like the towering, scaly predators on screen.
Pet Owners Independence Day
Pet Owners Independence Day was created by Ruth and Thomas Roy of Wellcat Holidays, with their page dating back to 2002. On this day, dog and cat owners take the day off work while their pets go in their place, since most pets are jobless, sleep all day, and don’t even take out the trash. It’s a tongue-in-cheek celebration giving pet owners a guilt-free excuse to lounge around and do absolutely nothing.
