Patriot Day
On this day, the American flag is to be flown at half-staff at individual American homes, at the White House, and on all U.S. government buildings, home and abroad. The President also asks Americans to observe a moment of silence beginning at 8:46 A.M. (Eastern Daylight Time). This is the time the first plane struck the North Tower of the World Trade Center on September 11, 2001.
