September 11, 2026, is the 254th day of the year, with 111 days remaining, and it falls on a Friday.
Today marks the twenty-fifth anniversary of the September 11, 2001 attacks, in which nearly 3,000 people lost their lives. The date was formally established as Patriot Day in 2001 under Public Law 107-89, signed by President George W. Bush, and in 2009 Congress passed the Edward M. Kennedy Serve America Act, officially designating it the National Day of Service and Remembrance. Flags are flown at half-staff and a moment of silence is observed nationwide. It is one of only two days, alongside Martin Luther King Jr. Day, recognized under federal law as a national Day of Service, and an estimated 35 million Americans mark it each year through volunteering and acts of community service. As 9/11 Day co-founder David Paine has put it, the goal was to make sure the terrorists did not have the last word in defining how the country would remember this date, choosing instead to answer it with service and unity.
A small number of lighter observances also fall on September 11. Libraries Remember Day, started by librarian Bill Erbes in Illinois, keeps library doors open each year as a quiet symbol of resilience. Women’s Baseball Day traces back to the All-American Girls Professional Baseball League, founded in 1943 to keep ballparks full while male players served overseas. And Stand Up To Cancer continues its work raising funds for cancer research through a nationwide televised broadcast.

Bravehearts Day
Bravehearts Day 🇦🇺 (formerly White Balloon Day) was established in 1997 by the Australian organization Bravehearts to raise awareness and funds for the prevention of child sexual abuse. Originally called White Balloon Day, it was one of the first initiatives in Australia to break the silence surrounding this issue, creating a cultural shift in how communities respond to survivors and work toward prevention. The rebranded Bravehearts Day continues to serve as a key event during National Child Protection Week, with fundraising efforts supporting education, training, and advocacy.
📝 In the United States, National BraveHearts Day is observed on April 28 to honor the bravery of families affected by pediatric cancer and to support childhood cancer research and treatment.

International Cloud Appreciation Day* (Second or third Friday in September) was created by the Cloud Appreciation Society, which has more than 60,000 members across 120 countries. The day encourages people to pause, look up, and enjoy the beauty and variety of clouds. Participants are invited to share photos in the Memory Cloud Atlas, an online archive documenting skies from around the world.

The observance promotes financial literacy and retirement planning, encouraging employees to review their retirement accounts and employers to provide guidance on savings. The date was chosen to tie into Labor Day, reminding people to link their work today with security for the future.
National Hot Cross Bun Day
National Hot Cross Bun Day is a modern, commercially driven holiday that brings this centuries-old Easter treat into the spotlight outside its traditional season. While hot cross buns have Christian roots dating back to medieval England, businesses such as Bakers Delight helped popularize a September celebration, encouraging people to enjoy the buns year-round.
National Make Your Bed Day
National Make Your Bed Day promotes the simple but powerful habit of bed-making. While its exact origins are unclear, the observance reflects ideas often echoed by military traditions and wellness advocates—that starting the day with a completed task creates momentum, organization, and a sense of accomplishment.
No News is Good News Day
No News is Good News Day takes its name from a proverb dating back to at least the early 1600s, attributed to King James I of England and later recorded by James Howell. The phrase suggests that in the absence of troubling updates, one can assume all is well. Today the observance encourages people to disconnect from the constant flow of information, finding peace in quiet and the absence of headlines.
Patriot Day
Patriot Day / September 11 National Day of Service and Remembrance was officially established in 2001 by Public Law 107-89, signed by President George W. Bush, to honor the nearly 3,000 lives lost in the terrorist attacks of September 11, 2001. It is a day of reflection and community service, with U.S. flags flown at half-staff and a moment of silence observed. The observance calls for transforming tragedy into unity through acts of kindness and civic engagement.
Stand Up To Cancer (SU2C) Day
Stand Up To Cancer (SU2C) Day* (Second Friday in September) is a global fundraising initiative launched in 2008 by nine women in the entertainment industry, including Katie Couric, Sherry Lansing, and Laura Ziskin, all of whom had personal connections to cancer. The movement pioneered a collaborative research model that brings scientists from different institutions together to accelerate discoveries and treatments. The first televised fundraising event reached millions, and SU2C has since raised hundreds of millions of dollars for innovative cancer research, honoring patients and supporting survivors worldwide.
Women’s Baseball Day
Women’s Baseball Day is observed annually on September 11th. It commemorates a game played in Springfield, Illinois in 1875 between two teams called the “Blondes” and the “Brunettes,” which is recognized as the first women’s baseball game where fans paid admission and players were paid. The day also honors the broader history of women in baseball, including the “Bloomer Girls” teams that toured the country from the 1890s through the 1930s and the All-American Girls Professional Baseball League, which had 600 women playing professionally between 1943 and 1954.
