Patriot Day is an annual observance in the United States, officially designated to commemorate the devastating terrorist attacks that occurred on September 11, 2001. While federally recognized as a national day of remembrance, it is crucial to clarify that Patriot Day is not classified as a federal public holiday in the traditional sense, which typically involves the closure of government offices and banks or a day off from work. Instead, its primary function is to serve as a solemn occasion for national reflection and memorialization. The designation of Patriot Day was established by a joint resolution of the U.S. Congress, signed into law by President George W. Bush on December 18, 2001 (Public Law 107-89), also known as the "9/11 Resolution." This resolution requests that the President issue an annual proclamation calling upon federal government departments, agencies, and instrumentalities to display the United States flag at half-staff from sunrise to sunset on September 11. Citizens are also encouraged to display the flag at half-staff and to observe a moment of silence beginning at 8:46 a.m. Eastern Daylight Time (the time the first plane struck the World Trade Center). The observance aims to honor the nearly 3,000 victims who perished, as well as the courage and sacrifices of first responders, law enforcement personnel, emergency workers, and military service members who acted heroically in the aftermath. Unlike a federal public holiday, which dictates a non-working day for federal employees, Patriot Day emphasizes commemorative ceremonies, acts of service, and personal reflection rather than a cessation of normal activities. ...
