The keyword term "Patriot Day" functions as a proper noun. The article's main point is to define this proper noun by clarifying its classification, specifically whether it qualifies as a holiday. Patriot Day, observed on September 11, is a national day of observance and remembrance in the United States, but it is not a federal holiday. Consequently, government offices, schools, and private businesses do not close.
The distinction lies in its legal and practical status. A federal holiday is established by law (Title 5 of the United States Code) and typically involves paid time off for federal employees and the closure of non-essential federal services. In contrast, Patriot Day was established by Public Law 107-89 as a discretionary day of remembrance. The proclamation calls upon the American people to observe the day with ceremonies, to display the flag at half-staff, and to observe a moment of silence beginning at 8:46 a.m. Eastern Daylight Time to honor the victims of the September 11, 2001 attacks.
Therefore, while Patriot Day carries significant national importance, its purpose is one of solemn commemoration rather than a day of leisure or celebration. In 2009, its name was expanded to "Patriot Day and National Day of Service and Remembrance," further emphasizing its function as a day for reflection and active community service, distinguishing it from the legal and social structure of a public holiday.
