Patriot Day is an annual observance on September 11 to remember those who were injured or died during the terrorist attacks in the United States on September 11, 2001. Many Americans refer Patriot Day as 9/11 or September 11.
What do people do?
On the direction of the President, the flag of the United States of America should be displayed on the homes of Americans, the White House and all United States government buildings in the whole world. The flag should be flown at half-mast as a mark of respect to those who died on September 11, 2001. Many people observe a moment of silence at 8:46 AM (Eastern Daylight Time). This marks the time that the first plane flew into the World Trade Center. Some communities, particularly in the areas directly affected by the attacks, hold special church services or prayer meetings. People who personally experienced the events in 2001 or lost loved ones in them may lay flowers or visit memorials.
