Many American service men and women lost their lives or were injured on December 7, 1941. National Pearl Harbor Remembrance Day is also referred to as Pearl Harbor Remembrance Day or Pearl Harbor Day. 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. The flag should be flown at half-mast to honor those who died in the attack on Pearl Harbor. Some organizations may hold special events in memory of those killed or injured in Pearl Harbor.
