Patriot Day occurs on September 11 of each year, designated in memory of the nearly three thousand who died in the September 11, 2001 attacks. On this day, the President directs that the flag of the United States be flown at half-staff and displayed from individual American homes, at the White House, and on all U.S. government buildings and establishments, home and abroad. The President also asks Americans to observe a moment of silence beginning at 8:46 A.M. (Eastern Daylight Time) marking the first plane crash on Sept. 11, 2001.
