The term "Patriot Day" is the proper noun designating the annual United States observance on September 11. It was established to remember and honor the 2,977 people killed in the terrorist attacks of September 11, 2001. Formally created by U.S. Public Law 107-89 on December 18, 2001, it is a national day of remembrance for the events at the World Trade Center in New York, the Pentagon in Virginia, and in Shanksville, Pennsylvania.
This observance is distinct from "Patriots' Day," a regional holiday in April commemorating the Revolutionary War Battles of Lexington and Concord. On Patriot Day (September 11), the President of the United States issues a proclamation directing that U.S. flags be flown at half-staff at all homes, the White House, and all government buildings and establishments. Americans are also asked to observe a moment of silence beginning at 8:46 a.m. Eastern Daylight Time, the moment the first plane struck the North Tower of the World Trade Center.
In addition to being a day of solemn remembrance, Congress designated Patriot Day as the National Day of Service and Remembrance in 2009. This legislation encourages Americans to participate in community service and charitable activities as a tribute to the victims, survivors, and first responders of 9/11. The day, therefore, serves a dual purpose: to memorialize the tragic loss of life and to promote a spirit of unity and service throughout the nation.
