National Pearl Harbor Remembrance Day

National Pearl Harbor Remembrance Day commemorates the December 7, 1941 attack on Pearl Harbor. It honors the service members and civilians who died and remembers the sacrifice associated with the event that brought the United States into World War II.

Federal law requests that the United States flag be flown at half-staff from sunrise until sunset on December 7. The annual direction applies nationwide, using local sunrise and sunset times.

Mast treats this as a recurring statutory observance rather than waiting for a new proclamation each year. The linked federal law remains the controlling source for the observance.
