National Pearl Harbor Remembrance Day, also referred to as Pearl Harbor Remembrance Day or Pearl Harbor Day, is observed annually in the United States on December 7, to remember and honor the 2,403 citizens of the United States who were killed in the Japanese surprise attack on Pearl Harbor in Hawaii on December 7, 1941.
On August 23, 1994, the United States Congress, by Pub.L. 103–308, designated December 7 of each year as National Pearl Harbor Remembrance Day. On Pearl Harbor Day, the American flag should be flown at half-staff until sunset to honor those who died as a result of the attack on U.S. Military and naval forces in Hawaii.
Pearl Harbor Day is not a federal holiday – government offices, schools, and businesses do not close. Some organizations may hold special events in memory of those killed or injured at Pearl Harbor.
