June 10, 2026, is the 161st day of the year, with 204 days remaining, and it falls on a Wednesday — in the twenty-third week of the year.
With 11 national and international days on the calendar, June 10 carries meaningful history: Alcoholics Anonymous was founded on this date in 1935 when Bill Wilson and Dr. Bob Smith first met in Akron, Ohio — a meeting that gave birth to a programme that has helped millions achieve sobriety in the 91 years since. László Bíró patented the ballpoint pen on June 10, 1943. And a deeply colored glass of Durif, a frosted cookie, a root beer float, and a tall iced tea are all waiting.

On June 10, 1935, Bill Wilson and Dr. Bob Smith met for the first time in Akron, Ohio — a conversation that gave birth to Alcoholics Anonymous and the twelve-step model of recovery that has since helped millions of people worldwide achieve sobriety. In 2026, AA celebrates its 91st anniversary. Members and recovery communities mark the day with gratitude meetings, sober events, and pilgrimages to Akron.
National Iced Tea Day
Iced tea is the most consumed tea in the United States — accounting for roughly 85% of all tea drunk in America — and one of the defining beverages of summer. Whether you prefer it sweetened Southern-style over crushed ice, unsweetened with lemon, or brewed into a Long Island, National Iced Tea Day on June 10 arrives at exactly the right moment in the calendar.
Durif Day / Petite Sirah Day
Durif — known in California as Petite Sirah — is a deeply coloured, heavily tannic red wine grape that produces some of the most intensely flavoured wines in the world: dark berries, chocolate, espresso, and black pepper in a full-bodied package that rewards both cellaring and bold food pairings. Durif Day on June 10 celebrates this underappreciated variety and the passionate community of producers and drinkers around it.
National Herbs and Spices Day
Herbs and spices are among the oldest traded commodities in human history — the spice trade shaped empires, drove exploration, and connected continents centuries before the internet. National Herbs and Spices Day on June 10 invites cooks of every level to experiment beyond their comfort zone: to reach for the sumac, the za’atar, the tarragon, or the smoked paprika they’ve been ignoring at the back of the cupboard.
Here’s every observance celebrated on June 10, 2026.
National & International Days on June 10
Whether you’re honoring AA’s founding, writing something with a ballpoint pen, sipping iced tea or Petite Sirah, cooking with herbs and spices you’ve been ignoring, eating an egg roll, or simply slowing down the way you speak today, here’s the story behind each of these June 10 celebrations.
Durif Day
Durif Day / Petite Sirah Day honors the Durif grape—a bold red variety first identified by French botanist François Durif in the 1860s. It was later named by ampelographer Victor Pulliat in 1868. DNA analysis in 1997 confirmed that Durif is a natural cross between Syrah and Peloursin. While nearly extinct in France today, Durif thrives in regions like California and Australia. The day highlights the grape’s long standing history, deep color, and transformation from use in fortified wines to modern full-bodied dry wines.

EHS Day
EHS Day, also known as National EHS Awareness Day, raises awareness about Electromagnetic Hypersensitivity (EHS), a condition where people report symptoms believed to be caused by electromagnetic fields. Though not widely recognized as a medical diagnosis, EHS has gained attention as our reliance on electronics grows. The day was founded by DefenderShield in 2020 to encourage education and understanding of this little-known issue.
National Ballpoint Pen Day
National Ballpoint Pen Day commemorates the U.S. patent filing for the ballpoint pen on June 10, 1943. The invention transformed how people wrote, offering a cleaner, more convenient alternative to fountain pens. It’s a great time to appreciate one of the most reliable writing tools in everyday life.

National Bed Bug Prevention Day
National Bed Bug Prevention Day was established in 2019 by Dodson Pest Control to draw attention to the growing problem of bed bug infestations. With increased travel and the pests’ ability to thrive in various environments, awareness about prevention is more important than ever. June 10 is a chance to learn about identifying bed bugs, preventing their spread, and protecting your home while on the move.
National Black Cow Day
National Black Cow Day celebrates the Black Cow, also known as a root beer float—a refreshing drink made by combining root beer and vanilla ice cream. Frank J. Wisner of Colorado is credited with creating the treat in 1893. Variations exist depending on region, but the classic combination remains a nostalgic favorite. The day invites everyone to enjoy this sweet blend of soda and ice cream.
National Egg Roll Day
National Egg Roll Day was founded by Van’s Kitchen in 2019. It honors both the egg roll and the founding of the company in June 1986. Egg rolls are a staple of American Chinese cuisine—crispy, savory rolls filled with meat and vegetables. Their exact origin is debated, but they likely emerged in New York in the 1930s. National Egg Roll Day celebrates this deep-fried favorite with its unique blend of history and flavor.
National Frosted Cookie Day
National Frosted Cookie Day was introduced by Mother’s® Cookies in May 2023. This fun holiday spotlights frosted animal cookies. Whether used in pretend adventures or enjoyed as a sweet treat, these colorful cookies are a favorite for families.
National Herbs and Spices Day
National Herbs and Spices Day honors the value herbs and spices bring to cooking. From fresh basil to ground cumin, these ingredients add flavor, color, and aroma to dishes. As grilling season picks up, this day invites home cooks to explore new blends and appreciate the essential role herbs and spices play in every kitchen.
National Iced Tea Day
National Iced Tea Day celebrates one of the most refreshing drinks of summer. Iced tea has roots in American culinary history going back to the 19th century, with the first known recipes appearing in the 1870s. Its popularity exploded after the 1904 World’s Fair in St. Louis, when a heatwave prompted a tea merchant to serve his brew over ice. Today, Americans consume billions of glasses each year—sweetened or unsweetened, with lemon or plain.
Talk Slow Day
Talk Slow Day was founded in 2024 by the Mid-Atlantic Aphasia Conference to promote clear and patient communication, especially when speaking to individuals with neurological communication disorders such as aphasia, dysarthria, or ADHD. It reminds people that slowing down speech can greatly improve understanding without resorting to condescension. The day emphasizes inclusion and respectful communication for those with language processing difficulties.
