National & International Days on April 11
Whether you’re visiting a museum, spoiling your pet, making a pot of cheese fondue, catching and releasing a fish, or finally clearing out that pantry shelf you haven’t touched since last spring, there’s something on this list for everyone. Here’s the story behind each of these April 11 celebrations.
Dog Therapy Appreciation Day
Dog Therapy Appreciation Day celebrates the dogs who bring calm and comfort to people in hospitals, nursing homes, schools, and disaster zones. The formal story begins with Elaine Smith, a registered nurse working in England, who noticed that a chaplain’s Golden Retriever was lifting patients’ spirits during ward visits. Back home in New Jersey in 1976, she founded Therapy Dogs International, the world’s first organization for testing and certifying dogs and their handlers to visit hospitals and nursing homes. The day itself was launched in 2020 by Pet Partners, one of the leading organizations in animal-assisted therapy.

International Louie Louie Day
International Louie Louie Day celebrates a song with one of the most unlikely histories in rock and roll. Louie Louie is a rhythm and blues song written, composed, and recorded by Richard Berry in 1956 and released in 1957, best known today for the Kingsmen’s 1963 recording. That version’s mumbled, garage-band vocals convinced worried parents that something indecent was buried in the lyrics, prompting a 31-month FBI investigation that ultimately concluded the bureau was “unable to interpret any of the wording in the record.” The song was unintelligible, not obscene, and all the fuss only made it more famous. The date also marks Richard Berry’s birthday, as he was born on April 11, 1935.
National Barber Shop Quartet Day
National Barber Shop Quartet Day commemorates the formation of the Society for the Preservation and Encouragement of Barber Shop Quartet Singing in America (SPEBSQSA) on April 11, 1938. The organization was founded by Owen C. Cash and Rupert I. Hall in Tulsa, Oklahoma, in 1938, when 26 men gathered on the roof garden of the Tulsa Club for an evening of four-part harmony.
National Catch and Release Day
National Catch and Release Day* (Second Saturday of April) highlights a fishing practice built around restraint. Rather than keeping what they catch, anglers return the fish to the water unharmed, allowing populations to stay healthy and reproduce naturally. The practice was formally introduced in Michigan in 1952 as a strategy to reduce the costs associated with stocking hatchery-raised trout, and was readily accepted by those fishing for sport rather than food.
National Cheese Fondue Day
National Cheese Fondue Day celebrates one of Switzerland’s most sociable dishes. Cheese fondue traces its roots to the Swiss Alps, where it emerged as a clever way for Alpine herders to make use of stale bread and aged cheese during the harsh winter months. It was promoted as a Swiss national dish by the Swiss Cheese Union in the 1930s, and introduced to American audiences at the Swiss Pavilion at the 1964 New York World’s Fair.
National Clean Up Your Pantry Day
National Clean Up Your Pantry Day was started in 2015 by Laura Fuentes, a nutritionist, author, and blogger who focuses on helping families eat better and stay organized. The premise is something most of us can relate to: the tin of chickpeas bought for a recipe you never made, the spices from three years ago, the pasta lurking at the back of the shelf behind everything else. This is the day to pull it all out, check what has expired, donate what is still good but unlikely to be used, and start fresh. A tidy pantry means less food waste, easier meal planning, and the small but satisfying feeling of actually knowing what you have.

National Eight Track Tape Day
National Eight Track Tape Day takes us back to the 1960s and 70s, when music was often played on endless-loop magnetic tape cartridges. Invented in 1964 by Bill Lear and other tech partners, 8-tracks were a popular format for car audio until the rise of compact cassettes. While now obsolete, these tapes are remembered fondly by collectors and music fans.
National Marketing Operations Appreciation Day
National Marketing Operations Appreciation Day was launched by Zapier, the workflow automation company, on April 11, 2022, to recognise the people who keep marketing teams running smoothly. Marketing operations professionals handle the data, tools, and systems behind campaigns that most people never think about. This day gives them a moment in the spotlight.
National Pet Day
National Pet Day, founded in 2005 by animal welfare advocate Colleen Paige, encourages pet lovers to remember the pets that may not have a forever home yet. While it’s a great day to spoil your own animals, the core message is to raise awareness for adoptable pets in shelters and the importance of rescue and responsible pet ownership.
National Poutine Day
National Poutine Day celebrates Quebec’s most famous culinary export. The dish was created in the Centre-du-Québec area in the late 1950s, with the name coming from Québécois slang meaning a mess. The classic combination of French fries, cheese curds, and brown gravy has since become widely considered Canada’s national dish, served everywhere from roadside diners to high-end restaurants. National Poutine Day was created in 2018 as a promotion for the dish.
National Ranch Water Day
National Ranch Water Day raises a glass to West Texas’s answer to a skinny margarita. Ranch Water is a mix of tequila, lime, and soda water, sometimes referred to as the unofficial cocktail of West Texas. The drink was created in Austin by Kevin Williamson, the owner of Ranch 616, who began adding mineral water to his margarita and gradually developed the recipe from there. National Ranch Water Day was created in 2021 by RANCH2O Spirits to celebrate the drink and promote their canned version.
National Submarine Day
National Submarine Day marks the day the U.S. Navy acquired its first modern submarine. On this date in 1900, the Navy purchased the USS Holland, designed by Irish-born John Philip Holland, for $150,000. It was the first submarine with the power to remain submerged for a considerable distance, a capability that changed naval warfare forever. Though a bill to make the day official passed the Senate in 1969, no presidential proclamation followed. Nevertheless, Navy veterans and enthusiasts continue to recognize the historic day each year.
Poet in a Cupcake Day
Poet in a Cupcake Day* (Friday of Take Your Poet to School Week) takes place on the Friday of Take Your Poet to School Week and was created by Tweetspeak, a poetry-loving collective that became part of T.S. Poetry Press in 2015. On this fun and quirky day, students and poetry fans are encouraged to bake or decorate cupcakes in honor of their favorite poets. It’s a joyful way to combine the sweetness of literature with the literal sweetness of dessert.
World Parkinson’s Day
World Parkinson’s Day marks the birthday of Dr. James Parkinson, the London physician who first described the disease in his 1817 essay On the Shaking Palsy. The day’s symbol is a red and white tulip, chosen in 2005 when a Dutch horticulturalist living with Parkinson’s created a new tulip variety and named it after Dr. Parkinson. A personal tribute that was later adopted as the official worldwide symbol of the disease.
Slow Art Day
Slow Art Day* (Dates change) was founded in 2009 by Phil Terry, after he spent an hour in front of a single painting at a museum and found the experience transformed how he saw it. Research shows that the average museum visitor spends only seconds in front of each artwork before moving on. Slow Art Day asks people to do the opposite, to choose just one piece and stay with it for ten full minutes. Museums around the world take part each year, and the results tend to surprise people. The longer you look, the more you see.
