The phrase "September 11 a national holiday" functions grammatically as a noun phrase. The core of this phrase is the proper noun "September 11," which refers to a specific date and the associated historical events. The subsequent element, "a national holiday," acts as an appositive noun phrase, which serves to rename, define, or classify the preceding noun. In this structure, the appositive makes a specific assertion about the status of September 11.
Factually, September 11 is not a federal holiday in the United States. Federal holidays are designated by the U.S. Congress and typically result in the closure of non-essential federal government offices and paid time off for federal employees. Instead, September 11 is officially designated as Patriot Day and is also a National Day of Service and Remembrance. This designation was established by law and presidential proclamation following the attacks. Observances for Patriot Day include a moment of silence at 8:46 a.m. (EDT), the time the first plane struck the World Trade Center, and the lowering of the American flag to half-staff at all U.S. government buildings and establishments worldwide.
The distinction between a day of observance and a federal holiday is significant. By designating September 11 as Patriot Day, the intent is to create a time for solemn remembrance, reflection, and civic engagement through service, rather than a day of leisure. This classification emphasizes remembering the victims, honoring the first responders and heroes, and encouraging Americans to engage in charitable acts. Therefore, describing the day as a "national holiday" is a common but inaccurate statement that misrepresents its official purpose and legal standing.
