Patriot Day
September 11
Patriot Day is a day of solemn remembrance and national unity. On September 11, 2001, America faced one of the darkest mornings in its history. What followed was an extraordinary demonstration of American character: first responders raced toward danger rather than away from it; citizens united across every background and belief; the country stood together in grief and resolve. Patriot Day honors the nearly 3,000 lives lost, the heroes who answered the call, and the spirit of unity that defines America in its finest hours.

What It Commemorates
Patriot Day commemorates the September 11, 2001 terrorist attacks, which claimed the lives of nearly 3,000 Americans in New York City, at the Pentagon in Virginia, and in Shanksville, Pennsylvania. It honors the victims, the firefighters, police officers, and emergency responders who gave their lives in service, the passengers of Flight 93 who acted with extraordinary courage, and all who have served in the national defense. Patriot Day is a day to remember that Americans stand together in the defense of liberty.
Historical Background
On the morning of September 11, 2001, coordinated terrorist attacks struck the World Trade Center, the Pentagon, and attempted a fourth attack stopped by the heroic passengers of United Airlines Flight 93 over Pennsylvania. The nation responded with remarkable unity and resolve. Congress passed the Patriot Day resolution in 2001 to permanently honor the victims and heroes of that day. Flags are flown at half-staff across the country each September 11.
Why It Matters
Patriot Day honors the courage of ordinary Americans in extraordinary moments — the firefighters, police officers, paramedics, military personnel, and civilians who acted with selfless heroism. It reaffirms the national commitment to defend freedom and to stand together when the nation is tested. It is a reminder that the American spirit is indomitable.
How Americans Observe It
Americans observe Patriot Day by flying flags at half-staff, attending memorial ceremonies, pausing for moments of silence at 8:46 a.m., volunteering in their communities, and visiting September 11 memorials.

About Patriot Day
What Patriot Day Commemorates
Patriot Day commemorates the September 11, 2001 terrorist attacks and honors the nearly 3,000 Americans who lost their lives that morning in New York City, at the Pentagon, and in a field near Shanksville, Pennsylvania. It also honors the extraordinary first responders who raced toward the towers when everyone else was fleeing, and the passengers of United Airlines Flight 93 who fought back against the hijackers with breathtaking courage.
Patriot Day is a day of solemn remembrance — and of deep gratitude for the unity, courage, and resilience that the American people demonstrated in the days, weeks, and months that followed.
Historical Background
On the morning of September 11, 2001, nineteen terrorists hijacked four commercial aircraft. Two planes were flown into the Twin Towers of the World Trade Center in New York City; one struck the Pentagon in Arlington, Virginia. A fourth plane, United Airlines Flight 93, was crashed into a field near Shanksville, Pennsylvania, after passengers and crew voted to storm the cockpit and overpower the hijackers.
2,977 people were killed that day — the deadliest attack on American soil since Pearl Harbor. Among them were 343 firefighters and 72 law enforcement officers who ran toward the towers.
President George W. Bush called September 11 "a day that tested our resolve." Congress passed a joint resolution establishing Patriot Day in 2001, designating September 11 as a permanent day of remembrance and requiring that flags be flown at half-staff.
Why It Matters
Patriot Day matters because it honors the best of the American character — the courage that emerged from the worst of circumstances. On September 11, ordinary Americans performed extraordinary acts: first responders ran toward the burning towers; volunteers lined up by the thousands to donate blood; communities across the country came together in grief and solidarity.
The passengers of Flight 93 — who had just minutes to decide what to do — voted together, called their families to say goodbye, and then charged the cockpit to prevent the hijackers from reaching Washington, D.C. Their act of collective courage under unimaginable pressure is one of the most remarkable stories in American history.
How Americans Observe It
Americans observe Patriot Day by flying flags at half-staff, attending memorial ceremonies, and pausing for moments of silence — at 8:46 a.m. (when the first plane struck) and 9:03 a.m. (when the second struck). Many Americans visit September 11 memorials, including the National September 11 Memorial & Museum in New York City, the Pentagon Memorial in Virginia, and the Flight 93 National Memorial in Shanksville, Pennsylvania.
Patriot Day is also observed as a national day of service and remembrance, encouraging Americans to volunteer in honor of those lost.
Connection to America 250
The attacks of September 11 were meant to break American resolve. Instead, they revealed it. In the days that followed, Americans came together across every difference — political, racial, regional — in a display of national unity that stirred the world.
As America marks 250 years, Patriot Day is a reminder that the republic has always faced threats — and that Americans have always risen to meet them. The courage displayed on September 11 and in the years that followed is part of the long American tradition of defending freedom at any cost.
Historical Note
The passengers of United Airlines Flight 93 voted together, called their families to say goodbye, and then stormed the cockpit to prevent the hijackers from reaching their target — believed to be the United States Capitol or the White House. Their collective act of courage under unimaginable pressure is one of the most remarkable stories of American heroism.
