Observed annually on September 11th, Patriot Day honors and remembers those who were injured or killed during the terrorist attacks on the U.S on September 11, 2001. During these terrorist attacks, almost 3,000 people were killed and over 6,000 people were injured. It is considered to be one of the deadliest terrorist attacks in world history and one of the most devastating attacks on the United States since the Japanese attacked Pearl Harbor on December 7, 1941.
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-staff 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.
