May 9, 2026, is the 129th day of the year, with 236 days remaining, and it falls on a Saturday — the second Saturday of May and the Saturday before Mother’s Day — in the eighteenth week of the year.

With 25 national and international days on the calendar, May 9 is one of the most observance-packed Saturdays in May, with a striking number falling here specifically because it’s the second Saturday in May.

May 9 is anchored by the Stamp Out Hunger Food Drive — the largest single-day food drive in the United States — alongside World Fair Trade Day, International Migratory Bird Day, and Europe Day marking the Schuman Declaration of 1950. The Saturday before Mother’s Day also brings its own cluster of meaningful observances, honoring birth mothers, babysitters, and the dog moms who will be celebrating right alongside everyone else tomorrow.

National and International Days on May 9

Whether you’re donating food to your letter carrier, practicing archery, celebrating your dog mom status, belly dancing, learning about fair trade, raising a glass of Moscato, staying up all night, or tearing that mattress tag off once and for all, here’s the story behind each of these May 9 celebrations.


Brunch for Lunch Day

Brunch for Lunch Day* (Day before Mother’s Day) invites people to share a late-morning meal with friends or family. The day highlights foods like waffles, omelets, and Bloody Marys while reminding us that meaningful conversations often happen over shared meals.


Cornelia de Lange Syndrome Awareness Day

Cornelia de Lange Syndrome Awareness Day* (Second Saturday in May) was founded in 1989 to bring attention to Cornelia de Lange Syndrome (CdLS), a rare genetic disorder that affects physical and cognitive development. The condition can lead to a wide range of symptoms, including distinctive facial features, developmental delays, and medical complications. The day promotes research, advocacy, and better diagnosis to support individuals and families affected by CdLS.


Europe Day

Europe Day honors peace and unity in Europe and commemorates the 1950 Schuman Declaration, which laid the foundation for the European Coal and Steel Community. This initiative eventually evolved into the European Union, now comprising 27 countries. Europe Day has been officially observed by EU institutions since 1985 and is a public holiday in some member states.


Hurray for Buttons Day

Hurray for Buttons Day highlights buttons—not only as fasteners on clothes but also as collectibles and decorative items. The earliest buttons date back to 5000 B.C. in the Indus Valley, although they weren’t used as fasteners until the 13th century.


⊛ A related celebration, National Button Day, falls on November 16 and focuses more on button collecting as a hobby.


National Alphabet Magnet Day

National Alphabet Magnet Day was established in 2022 by The Type Set Co. to promote playful learning, literacy, and design using alphabet magnets. It’s a nod to childhood memories, clever phrases on fridges, and the joy of rearranging letters into messages.


National Archery Day

National Archery Day* (Second Saturday in May) was founded by the National Archery in the Schools Program (NASP) in 2015. It celebrates one of the world’s oldest sports. Archery dates back thousands of years and has featured in the Olympics since 1900. The day coincides with NASP’s national tournament in Louisville, Kentucky—an event that brings together thousands of young archers annually.


National Babysitter’s Day

National Babysitter’s Day* (Saturday before Mother’s Day) was created by SafetyWhys.com in 2003. It recognizes the dedication and care provided by babysitters across the country. It serves as a time to thank them for their hard work in providing safe and nurturing environments for children, particularly on weekends and holidays when families often need extra help.


National Birth Mother’s Day 

National Birth Mother’s Day * (Saturday before Mother’s Day) was founded in 1990 by Mary Jean Wolch-Marsh to honor biological mothers who have placed their children for adoption. It serves as a day of support and recognition, offering space to acknowledge the emotions and choices of birth mothers. It is observed the day before Mother’s Day to ensure these women are not overlooked.


National Butterscotch Brownie Day

National Butterscotch Brownie Day honors blondies—brownies made without cocoa that predate their chocolate cousins. Butterscotch brownies gained popularity in the 19th century and are made with brown sugar, butter, vanilla, and sometimes nuts or chips.


🍫 A related day, National Brownie Day, is observed on December 8 and focuses on the chocolate variety.


National Dog Mom’s Day

National Dog Mom’s Day* (Second Saturday in May): Founded in 2018 by Dig – The Dog Person’s Dating App, this day celebrates the special bond between women and their canine companions. It recognizes the love, care, and loyalty dog moms provide every day, from adopting rescue pups to nurturing lifelong connections.


🐶 This day complements National Pet Day on April 11 and National Dog Day on August 26.


National Home Front Heroes Day

National Home Front Heroes Day was first proposed in 2019 by World War II veteran John “Lucky” Luckadoo to honor the civilians who support military personnel by managing households, businesses, and communities while their loved ones serve. In 2022, a formal effort to designate May 9 as National Home Front Heroes Day gained traction in Congress, with bipartisan backing.


🪖 It complements National Military Spouse Appreciation Day, also observed on this day.


National Lost Sock Memorial Day

National Lost Sock Memorial Day honors the many socks that mysteriously vanish, leaving their partners behind. It is a humorous tribute to this common laundry mystery, inviting people to let go of unmatched socks and perhaps repurpose them creatively.


National Miniature Golf Day 

National Miniature Golf Day * (Second Saturday in May): Separate from the global Miniature Golf Day on September 21, this U.S.-focused celebration honors the enjoyment mini-golf brings. Early forms date back to 1912 in England, but it was Garnet Carter’s 1927 “Tom Thumb Golf” that brought standardized minigolf to the U.S. The day spotlights obstacles, themed courses, and friendly competition, making it popular for families and casual players.


⛳️ Related observances include National Golf Lover’s Day on October 4 and National Golf Month in August.


National Moscato Day

National Moscato Day was founded in 2012 by the Gallo Family Vineyards to celebrate one of the world’s oldest and most fragrant wine grape varieties. The Muscat grape family includes over 200 types and can produce wines that are sweet, dry, sparkling, or still. This day invites wine enthusiasts to explore its floral aromas and flavors.

National Train Day 

National Train Day * (Second Saturday in May) was created by Amtrak in 2008 to commemorate the 1869 completion of the first transcontinental railroad.

National Windmill Day

National Windmill Day 🇬🇧* (Second Saturday in May) is part of the UK’s National Mills Weekend. It is coordinated by the Wind and Watermills section of the Society for the Protection of Ancient Buildings. Each year, hundreds of preserved windmills and watermills open their doors to the public, offering guided tours and historical demonstrations. Radio clubs also participate by operating amateur stations from mill sites. The day celebrates these historic structures not just as engineering marvels, but also as symbols of agricultural and industrial heritage.


Stamp Out Hunger Food Drive Day 

Stamp Out Hunger Food Drive Day * (Second Saturday in May) was launched nationally in 1991 by the National Association of Letter Carriers, is the country’s biggest single-day food collection event. Carriers collect non-perishable food donations along their routes in over 10,000 cities and towns, helping restock food banks as post-holiday supplies dwindle.


Stay Up All Night Day

Stay Up All Night Day * (Second Saturday in May) was created to acknowledge night shift workers and celebrate nocturnal lifestyles. It blends appreciation with fun. It reflects how nighttime activity—from historical fire watches to modern 24/7 work culture—has shaped society. Observants might stay up with friends, watch movies, or explore quiet nighttime routines.


Tear the Tags Off the Mattress Day

Tear the Tags Off the Mattress Day pokes fun at the long-held myth that removing mattress tags is illegal. While the warning is meant for manufacturers to ensure transparency in materials, consumers often feel rebellious removing them. The day playfully invites people to embrace that moment of harmless rule-breaking—and maybe rip the tags off their pillows, too.


World Belly Dance Day 

World Belly Dance Day * (Second Saturday in May) was launched in 2008 by the World Belly Dance Alliance. It celebrates the art, expression, and cultural roots of belly dancing.
