September 10, 2026, is the 253rd day of the year, with 112 days remaining, and it falls on a Thursday.
With 9 national and international days on the calendar, September 10 is a lighter count than the days around it, but it carries real weight. World Suicide Prevention Day, established in 2003 by the International Association for Suicide Prevention and the World Health Organization, unites communities worldwide with the message that suicide is preventable.
Are You Okay Day, founded in 2009 by Gavin Larkin in honor of his father, lands on the same date this year, encouraging Australians to check in on the people around them. National TV Dinner Day celebrates the 1953 debut of the Swanson TV Dinner, the frozen meal that changed how America ate in front of the television. And International Make-Up Day carries two meanings, originally created to mend broken relationships, though it’s since also been claimed by some as a day for cosmetics.

National & International Days on September 10
Here’s a closer look at the 9 national and international days celebrated on September 10.
Are You Okay Day
Are You Okay Day / R U OK? Day 🇦🇺* (Second Thursday in September) is Australia’s national day of action encouraging people to check in on each other’s mental health by asking, “Are you OK?” Founded in 2009 by Gavin Larkin after losing his father to suicide, the day aims to break stigma, foster connection, and remind everyone that a single conversation can change a life.
National Anti-Junk Light Day
National Anti-Junk Light Day was founded in 2018 by TrueDark to draw attention to the harmful effects of artificial light on health and the environment. Often called “junk light,” the glow from electronic screens, LED bulbs, and other artificial sources can disrupt circadian rhythms, contribute to sleep problems, strain the eyes, and increase light pollution. The day encourages people to make mindful choices—like reducing screen time before bed, using blue-light filters, and embracing natural daylight—to protect both personal well-being and the planet.
National Port Wine Day
National Port Wine Day commemorates the creation of the Douro Demarcated Region in Portugal in 1756—the world’s first officially defined and regulated wine region. Established by the Marquis of Pombal, this historic step safeguarded the quality and authenticity of Port wine, ensuring its reputation as one of the world’s most distinctive fortified wines. The observance was launched in 2014 by the Port and Douro Wines Institute to honor this legacy, promote cultural heritage, and encourage appreciation of Port in all its styles—from ruby and tawny to vintage and white.
National Swap Ideas Day
National Swap Ideas Day highlights the power of collaboration and exchanging perspectives. Founded by holiday creator Robert Birch, it encourages people to share thoughts, solutions, and innovations in order to spark creativity and problem-solving. The observance reminds us that breakthroughs often emerge when diverse viewpoints come together—whether in classrooms, workplaces, or casual conversations. By opening ourselves to others’ ideas, we not only expand our own thinking but also strengthen community bonds and foster collective progress.
National School Picture Day
National School Picture Day* (Second Thursday in September) was founded in 2019 by Lifetouch, a company that has specialized in student photography since 1936. It honors the tradition of school portraits that chronicle a child’s growth, foster community through yearbooks and composites, and preserve treasured family memories.
National TV Dinner Day
National TV Dinner Day celebrates the 1953 debut of the Swanson TV Dinner, a frozen meal packaged in an aluminum tray designed to be eaten in front of the television. The first offering was a Thanksgiving-style meal of turkey, peas, cornbread dressing, and sweet potatoes. This invention transformed the frozen food industry, catering to the growing television culture of mid-20th-century America. By making convenient, ready-to-heat meals accessible to households, it reflected broader cultural shifts in family life, consumer habits, and entertainment.
World Suicide Prevention Day
World Suicide Prevention Day (WSPD) was established in 2003 through collaboration between the International Association for Suicide Prevention (IASP) and the World Health Organization (WHO). Observed globally on September 10 each year, it unites communities, governments, and organizations with the message that suicide is preventable. The day highlights the importance of awareness, education, and support, while honoring those lost to suicide and offering hope to those who struggle. With nearly 800,000 lives lost to suicide each year worldwide, WSPD serves as both a call to action and a gesture of solidarity, aiming to reduce stigma and strengthen prevention strategies.
