The keyword term "Patriot Day September 11" functions as a proper noun. It is the official name for the annual day of observance in the United States held on September 11 to commemorate the 2,977 people killed in the terrorist attacks of September 11, 2001. This designation was established by U.S. Public Law 107-89, a joint resolution of Congress that was signed into law on December 18, 2001, officially designating September 11 of each year as "Patriot Day."
On this national day of remembrance, the President of the United States issues a proclamation directing that the American flag be flown at half-staff at all U.S. government buildings and establishments worldwide. Americans are also called upon to observe a moment of silence, typically at 8:46 a.m. Eastern Daylight Time, the moment the first plane struck the North Tower of the World Trade Center. In 2009, the day was additionally designated as a National Day of Service and Remembrance, encouraging volunteerism and charitable activities. It is important to note that this is a national observance and not a federal holiday, meaning schools, government offices, and businesses generally remain open.
The purpose of the day is to provide a solemn occasion for national reflection on the tragedy of the attacks and their lasting impact. It serves as a tribute to the victims, their families, and the first responders who demonstrated extraordinary heroism. The observance is intended to foster a sense of national unity and resilience, ensuring that the events of that day are remembered and understood by subsequent generations as a pivotal moment in the nation's history.
