September 11 is observed in the United States as Patriot Day, a national day of remembrance. The term for this observance, "Patriot Day," functions as a proper noun, which is a name used for an individual place, organization, or, in this case, a specific day. It is not a federal holiday, but rather a day designated to commemorate the individuals who were killed in the September 11, 2001, terrorist attacks.
The designation was established by U.S. Public Law 107-89, signed by President George W. Bush on December 18, 2001. This law directs that the President call on all departments and citizens of the United States to display the flag at half-staff on Patriot Day. It also requests a moment of silence to be observed to honor the victims. In 2009, Congress designated September 11 as a National Day of Service and Remembrance, encouraging Americans to engage in charitable service as a tribute to the victims, survivors, and first responders.
The practical application of this observance differs significantly from a federal holiday. Government agencies, schools, and businesses generally do not close. Instead, the day is marked by memorial ceremonies, prayer services, and volunteer activities. The purpose is not for leisure or celebration, but for somber reflection on the loss of life and the national response to the attacks, emphasizing themes of unity, service, and resilience.
