The keyword term's main point, "Patriot Day," functions as a proper noun. Patriot Day is an annual observance in the United States on September 11. It commemorates the 2,977 people killed in the terrorist attacks of September 11, 2001.
Established by a presidential proclamation in December 2001, and later designated by law as the "Patriot Day and National Day of Service and Remembrance" in 2009, the day is marked by specific customs. The U.S. flag is flown at half-staff at all government buildings and individual American homes. Many organizations and communities observe a moment of silence at 8:46 a.m. (Eastern Daylight Time), the time the first plane struck the North Tower of the World Trade Center. It is important to distinguish this observance from Patriots' Day, a public holiday in Massachusetts and Maine on the third Monday of April, which commemorates the Battles of Lexington and Concord.
Unlike federal holidays, Patriot Day is a national observance where businesses and government offices do not typically close. The day is intended as a solemn occasion for remembrance, reflection, and national unity. The designation as a National Day of Service and Remembrance also encourages Americans to participate in community service and volunteer activities as a tribute to the victims, survivors, and first responders of the 9/11 attacks.
