Memorial Day is a federal holiday for remembering the people who died while serving in the country’s armed forces. Memorial Day is observed every year on the last Monday of May; and honors all Americans who died while in the military service.
In 1971, Congress passed the Uniform Monday Holiday Act and established that Memorial Day was to be celebrated on the last Monday of May.
Memorial Day is celebrated at Arlington National Cemetery each year with a ceremony in which a small American flag is placed on each grave. Traditionally, the President or Vice President lays a wreath at the Tomb of the Unknown Soldier. About 5,000 people attend the ceremony annually.
