The term "Patriot Day USA" functions grammatically as a proper noun phrase. The core element, "Patriot Day," is a compound proper noun that names a specific, official day of observance. The subsequent proper noun "USA" acts as a locative specifier, clarifying the national context of the observance. This phrase identifies the American day of remembrance held annually on September 11.
This day was formally established by U.S. Public Law 107-89, signed on December 18, 2001. The law designates September 11th of each year as "Patriot Day" to honor the individuals who lost their lives as a result of the terrorist attacks against the United States on September 11, 2001. Federal statute directs that the flag of the United States be flown at half-staff on all government buildings and establishments. It also requests that Americans observe a moment of silence at 8:46 a.m. Eastern Daylight Time, marking the time of the first aircraft impact.
In practice, the observance is a day of solemn remembrance and reflection. In 2009, congressional action also designated it as the "National Day of Service and Remembrance." This encourages Americans to engage in charitable service and community projects as a positive and forward-looking tribute. This dual designation combines a tribute to the victims, survivors, and first responders with an emphasis on national unity and civic engagement.
