Congenital Diaphragmatic Hernia Action Day
Congenital Diaphragmatic Hernia Action Day raises awareness about CDH, a birth defect in which the diaphragm fails to form completely, allowing abdominal organs to push upward into the chest and compress the developing lungs. David Y. Ige, former Governor of Hawaii, launched the observance to push for greater public understanding of a condition that affects roughly 1 in 2,500 newborns worldwide. CDH International, the world’s oldest and largest CDH charity, has supported families across more than 80 countries since its founding in 1995 as CHERUBS. The April 19 date was chosen in 2010 when a trademark on the phrase “Congenital Diaphragmatic Hernia Awareness” was finally removed, freeing the community to unite on a single day.
ℹ️ 1 in 2,500 newborns affected · CDH International founded 1995 · recognized by governments on six continents
Go Fly a Kite Day
Go Fly a Kite Day* (Third Sunday in April) celebrates one of humanity’s oldest airborne pastimes. Kites originated in China more than 2,000 years ago, where they were used to measure distances, send military signals, and eventually just for the pleasure of it. Spring’s reliable winds make this the natural season to get outside, let the wind run through your fingers, and watch your kite flying high until it is barely a speck against the clouds.
🪁 A similar day, National Kite Day, is celebrated on February 8.
Humorous Day
Humorous Day falls in April, which has been celebrated as National Humor Month since comedian and bestselling humor author Larry Wilde established it in 1976 with the specific goal of using laughter to improve wellbeing. Humorous Day operates as a mid-month reminder that laughter lowers cortisol, eases pain perception, and strengthens the immune system.

National Amaretto Day
National Amaretto Day celebrates the almond-flavored liqueur known for its smooth taste. According to the most popular story, a young widowed innkeeper in Saronno, Italy, posed as the Madonna for painter Bernardino Luini, who had been commissioned in 1525 to create frescoes for the church of Santa Maria dei Miracoli. In gratitude, she presented him with apricot kernels steeped in brandy. Centuries later, the Di Saronno family began producing the recipe commercially under the Disaronno Originale name, now the world’s best-selling amaretto. The name comes from the Italian word amaro, meaning bitter, giving amaretto its translation of a little bitter.

National Chicken Parmesan Day
National Chicken Parmesan Day was declared by Romano’s Macaroni Grill to mark the anniversary of its very first location, which opened on that date in 1988. The day was the brainchild of the chain’s founder, Phil Romano, whose original recipe book featured chicken parmesan as a signature dish from day one. It’s a good excuse to sit down with a plate of breaded chicken, tomato sauce, and melted cheese, whether you cook it at home or let a restaurant do the work.

National Dog Parent Appreciation Day

National Garlic Day
National Garlic Day: Garlic has flavored meals and healed ailments for over 7,000 years. Originally from Asia and now used worldwide, garlic belongs to the lily family alongside onions and leeks. It has long been praised for its medicinal properties, from boosting immunity to reducing cholesterol. Ancient beliefs also gave garlic a mystical status, thought to ward off evil spirits, witches, and even vampires.
National Hanging Out Day
National Hanging Out Day encourages people to skip the clothes dryer and air-dry their laundry on a clothesline instead. Alexander Lee founded Project Laundry List in New Hampshire in 1995 after his own town banned outdoor clotheslines, which he thought was both absurd and wasteful. He turned the cause into an annual observance, officially established in 1998, to highlight how much energy Americans burn unnecessarily on tumble drying. Clothes dryers account for up to 10 percent of residential energy use, and a backyard line or indoor drying rack is free, gentler on fabrics, and leaves clothes smelling of fresh air rather than synthetic fragrance.

National North Dakota Day
National North Dakota Day celebrates the 39th state to join the Union, a wide-open landscape of rolling prairies, Badlands, oil country, and some of the darkest night skies in North America. The day was established in 2017 by National Day Calendar as part of a series honoring each U.S. state in the order it achieved statehood. North Dakota was admitted on November 2, 1889, and its nickname, the Peace Garden State, comes from the International Peace Garden on the Canadian border, a 2,339-acre park dedicated to the friendship between the two nations. Theodore Roosevelt, who ranched in the Badlands in the 1880s, later said he would never have become president without his time in North Dakota.

Annual memorial events continue to be held in Oklahoma City and beyond.
National Poker Day
National Poker Day is celebrated by card players and strategy lovers alike.

The day, which emerged in the 2000s, celebrates poker’s long history, its mix of skill and luck, and the communities built around it.
National Primrose Day
National Primrose Day 🇬🇧 commemorates the death of British statesman Benjamin Disraeli on April 19, 1881. The primrose—Disraeli’s favorite flower—became a symbol of remembrance. Since the 1920s, primroses have been laid at his tomb and at his statue near Westminster Abbey each year on this date.

National Yahtzee Day
National Yahtzee Day marks April 19, 1956, the date on which toy entrepreneur Edwin S. Lowe filed Yahtzee as a trademark with the U.S. Patent Office. The game itself was invented a few years earlier by an anonymous Canadian couple who played a five-dice game called The Yacht Game with friends aboard their boat, then approached Lowe to produce sets as gifts, handing over the rights in exchange for 1,000 printed copies. Lowe recognized the commercial potential, renamed the game, and when advertising failed to communicate its appeal, invented the Yahtzee party, inviting people to play in person. Word of mouth did the rest. Over 50 million copies have since been sold.

Poetry & The Creative Mind Day
Poetry and The Creative Mind Day was established in 1996 by the Academy of American Poets as part of the inaugural National Poetry Month, itself launched that year as the largest literary celebration in the world. The Academy founded the month to give poetry the kind of dedicated cultural recognition already given to Black history in February and women’s history in March. Starting in 2002, the Academy introduced the annual Poetry and The Creative Mind gala, a free public reading that has featured Meryl Streep, Liam Neeson, Paul Simon, Patti Smith, and Malala Yousafzai, among many others, each sharing a poem that matters to them.

Sylvester the Cat Birthday
Sylvester the Cat Birthday marks April 19, 1945, the date the tuxedo-coated, lisping, perpetually unsuccessful cat first appeared on cinema screens in the Looney Tunes short “Life with Feathers.” Animator Friz Freleng created him, gave him the catchphrase “Sufferin’ succotash,” and paired him with Tweety Bird in one of animation’s most enduring rivalries. Sylvester never once caught that bird. Over the following decades he appeared in more than 100 cartoons, with Mel Blanc providing his distinctive voice for 44 years.
