In the United States, September 11th is designated as Patriot Day. The key term for this observance, "Patriot Day," functions as a proper noun. As a proper noun, it names a specific, official day of remembrance, distinguishing it from general descriptive terms.
Patriot Day was established by presidential proclamation following a joint resolution of the U.S. Congress (Pub.L. 10789) on December 18, 2001. It is a national day of observance to remember and honor the 2,977 people who were killed in the September 11, 2001 terrorist attacks. The U.S. flag is directed to be flown at half-staff on all federal buildings and establishments. The resolution also calls for a moment of silence to be observed nationwide at 8:46 a.m. Eastern Daylight Time, the time the first plane struck the North Tower of the World Trade Center. In 2009, the day was also officially designated as the National Day of Service and Remembrance, encouraging Americans to engage in volunteer work and charitable activities.
It is important to note that Patriot Day is a national observance, not a federal holiday. Consequently, government offices, schools, and businesses generally do not close. The day's purpose is one of solemn commemoration and reflection on the lives lost, the heroism of first responders, and the national unity experienced in the wake of the attacks. It serves as an annual, formal occasion for remembrance rather than a celebratory event.
