National & International Days on March 10
Below is a list of all 19 national and international days observed on March 10, each explained briefly.
Festival of Life in Cracks Day
Festival of Life in Cracks Day celebrates the stubborn persistence of nature — the small plants, flowers, and moss that push through sidewalk cracks, stone walls, and parched desert floors. Attributed to Thomas and Ruth Roy of Wellcat Holidays, the day encourages people to pause and appreciate the tiny, resilient miracles of nature we usually walk right over.
Histotechnology Professionals Day
Histotechnology Professionals Day, established in 2010 by the National Society for Histotechnology, honors the histotechnologists (HT) and histotechnicians (HTL) who prepare tissue samples for microscopic examination by pathologists to diagnose diseases like cancer.
International Bagpipe Day
International Bagpipe Day was established in 2012 by the Bagpipe Society and the International Bagpipe Organisation to celebrate the surprising diversity of an instrument most people associate solely with Scotland. In fact, there are over 130 types of bagpipes found across Europe, North Africa, and Western Asia, from the famous Great Highland Bagpipe to countless lesser-known varieties.
International Day of Awesomeness
International Day of Awesomeness encourages everyone to embrace their unique qualities and perform their own feats of awesomeness, guided by the tagline “No one’s perfect, but everyone can be awesome.” The day was conceived in 2007 by web developer Kevin Lawver and is held on Chuck Norris’s birthday as a nod to the martial artist’s legendary pop culture status.
International Day of Women Judges
International Day of Women Judges was established by the United Nations General Assembly in 2021 to highlight the importance of women in the judiciary. First observed globally on March 10, 2022, it promotes gender equality, judicial integrity, and inclusivity in legal systems worldwide.
International Wig Day
International Wig Day was created in 2016 by Danish costume shop Temashop to encourage everyone to embrace wigs as a playful form of self-expression, while also shining a light on the emotional and personal significance wigs hold for those experiencing medically caused hair loss.
Mario Day
Mario Day, also written as Mar10, celebrates Nintendo’s most iconic character on the date that spells his name. First appearing as Jumpman in Donkey Kong in 1981 before becoming the world’s most famous plumber in Super Mario Bros. in 1985, Mario has grown into a global pop culture icon — and while no official founder exists, the day is now widely celebrated by video game fans around the world.
National Blueberry Popover Day
National Blueberry Popover Day celebrates light, hollow pastries that puff up while baking, similar to Yorkshire pudding. The first known reference to popovers dates back to 1850, and the first cookbook to feature a recipe was Practical Cooking by M.N. Henderson in 1876. This day highlights the blueberry-filled variation of the dessert.
National Landline Telephone Day
National Landline Telephone Day commemorates March 10, 1876, when Alexander Graham Bell successfully transmitted the first intelligible speech over a wire, famously calling out to his assistant: “Mr. Watson, come here, I want to see you.” The day celebrates the technology that connected the world for over a century, tracing its journey from hand-cranked wall units and rotary phones to the touch-tone landlines that became a fixture in homes across the globe.
National Milky Way Day
National Milky Way Day marks the anniversary of the bar’s official trademark registration in 1925. Created by Frank C. Mars in 1923 and inspired by popular malted milkshakes of the era, the Milky Way was introduced nationally in 1924 and generated $800,000 in sales in its first year.
National Organize Your Home Office Day
National Organize Your Home Office Day* (Second Tuesday in March) was established by organization expert Lisa Kanarek to encourage people to declutter and reorganize their home workspaces. The idea is simple: a tidy, well-organized office reduces stress and makes it easier to focus and get things done.
National Pack Your Lunch Day
National Pack Your Lunch Day encourages people to bring their own meals to work, school, or wherever they spend their day. Packing lunch not only saves money but also allows for better portion control and healthier meal choices.
National Peel Day
National Peel Day was established in 2020 by PCA SKIN® to demystify chemical peels and challenge the misconception that they are painful or require lengthy recovery time. The day educates consumers about the benefits of modern, gentle peel formulations as a safe and effective way to maintain healthy skin.
National Ranch Day
National Ranch Day was officially established in 2018 by Hidden Valley Ranch to celebrate America’s most popular salad dressing, which has topped the charts since 1992. The original buttermilk recipe was developed in 1949 by Nebraska-born Steve Henson, who later opened Hidden Valley Ranch in California, where the dressing became so popular that he began selling it in dry mix packets before selling the brand to Clorox for $8 million in 1972.
National Sending Day
National Sending Day was established in 2021 by Sendoso to encourage people to step away from emails and digital messages and reconnect through something tangible, whether a handwritten note, a box of cookies, or a personalized gift. The idea is simple: receiving something physical creates a stronger emotional connection than anything that lands in an inbox.
National Skirt Day
National Skirt Day encourages people to wear any style of skirt and celebrate one of humanity’s oldest garments. Skirts have existed for thousands of years and were worn by both men and women in ancient cultures. The oldest known skirt, made of straw, dates back nearly 5,900 years and was found in Armenia.
National Women and Girls HIV/AIDS Awareness Day
National Women and Girls HIV/AIDS Awareness Day, led by the Office on Women’s Health, exists to close the gap between women and men in HIV/AIDS awareness, testing, and treatment. The day shines a light on the disproportionate impact of the virus on women and girls, particularly women of color, and urges communities to take action on prevention and care.
Paper Money Day
Paper Money Day marks March 10, 1862, when the U.S. government issued its first paper currency — in denominations of $5, $10, and $20 — to help finance the Civil War. Printed with green ink on the back to deter counterfeiting, the notes quickly earned the nickname Greenbacks and replaced the unreliable patchwork of privately issued bank notes and coins that Americans had relied on until then.
Salvation Army Day
Salvation Army Day marks March 10, 1880, when Commissioner George Scott Railton and seven female officers, known as the Hallelujah Lassies, landed at Battery Park in New York City to establish the organization in the United States. The day honors the Salvation Army’s 145-year legacy of providing food, shelter, spiritual support, and disaster relief to those in need across the country.
