September 11, Monday
In the United States, Patriot Day occurs on September 11 of each year in memory of the people killed in the September 11 attacks of the year 2001.
The flag of the United States is flown at half-staff at the White House and on all U.S. government buildings and establishments throughout the world; Americans are also encouraged to display flags in and outside their homes. Additionally, a moment of silence is observed to correspond with the attacks, beginning at 8:46 a.m. (Eastern Daylight Time), the time the first plane, American Airlines Flight 11, struck the North Tower of the World Trade Center on September 11, 2001.
Patriot Day is not a federal holiday; schools and businesses remain open in observance of the occasion, although memorial ceremonies for the 2,977 victims are often held. Volunteer and service opportunities are coordinated by the Corporation for National and Community Service.
