What Is the Pearl Harbor Date?
The official Pearl Harbor date is December 7, 1941. Early on that Sunday morning, aircraft from the Imperial Japanese Navy attacked the U.S. Pacific Fleet stationed at Pearl Harbor.
The attack began shortly before 8:00 a.m. local time and lasted approximately two hours. Despite its relatively short duration, the assault caused devastating damage to American military forces.
Why Did Japan Attack Pearl Harbor?
Japan’s leaders believed that a surprise strike against the United States would weaken American naval power in the Pacific. At the time, tensions between Japan and the United States had been increasing due to economic sanctions, trade restrictions, and competing interests in Asia and the Pacific region.
Japanese military planners hoped that disabling the U.S. Pacific Fleet would prevent American interference with Japan’s expansion plans. However, the attack ultimately had the opposite effect by uniting American public opinion in support of entering World War II.

The attack involved hundreds of Japanese aircraft, including bombers, torpedo planes, and fighter planes.
Major targets included:

Several American battleships were sunk or heavily damaged, including the famous battleship USS Arizona, which remains a memorial site today.
