In the United States, September 11 is officially designated as Patriot Day. It is also recognized as the National Day of Service and Remembrance. This date is not a federal holiday, during which non-essential government offices and most businesses close, but rather a national observance for commemorating the individuals killed in the terrorist attacks of September 11, 2001.
The name "Patriot Day" was established following the attacks through U.S. Congressional action. On December 18, 2001, Public Law 107-89 was signed, requesting that the President issue an annual proclamation designating September 11 as Patriot Day. In 2009, the Edward M. Kennedy Serve America Act was passed, which also designated the date as a National Day of Service and Remembrance. This legislation aimed to encourage volunteerism and charitable work as a tribute to the victims, survivors, and first responders.
The observance of the day embodies these two distinct but related titles. As Patriot Day, it is a time for solemn commemoration, with federal law directing that the American flag be flown at half-staff on all U.S. government buildings and establishments. It is also customary to observe moments of silence that correspond with the times of the attacks. As the National Day of Service and Remembrance, it serves as a practical call to action, encouraging individuals to engage in community service to honor the spirit of unity that emerged following the tragedy.
