The attack on Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Territory of Hawaii, just before 8:00 a.m. (local time) on Sunday, December 7, 1941.
The United States was a neutral country at the time; the attack led to its formal entry into World War II the next day.
