On Pearl Harbor Day, the American flag should be flown at half-staff to honor those that died in the attack on U.S. military forces in Hawaii. Pearl Harbor Day is not a federal holiday and government offices and businesses remain open. On December 7, 1941, Japan attacked Pearl Harbor. The attack killed 2,403 Americans and injured 1,178 others. It destroyed four battleships and damaged four others. The attack also sunk three cruisers, three destroyers, and one minelayer. Aircraft losses were 188 destroyed and 159 damaged. Each year in the US, National Pearl Harbor Remembrance Day honors all those who lost their lives when Japan attacked Pearl Harbor on December 7.

National Pearl Harbor Remembrance Day is observed annually in the United States on December 7

In August 1994, the United States Congress designated December 7 as National Pearl Harbor Remembrance Day. Every year, thousands of Americans gather at military memorials, churches and other venues to pay their respects to those who died in the attack on Pearl Harbor.
