Memorial Day is a federal holiday observed annually in the United States on the last Monday of May. Formerly known as Decoration Day, it originated after the American Civil War to commemorate the fallen Union soldiers of the Civil War. By the 20th century Memorial Day had been extended to honor all Americans who have died in all wars. Memorial Day was not declared an official holiday by Federal law until 1967. On June 28, 1968, the Congress passed the Uniform Holidays Bill, which moved four holidays, including Memorial Day, from their traditional dates to a specified Monday in order to create a convenient three-day weekend. The change moved Memorial Day from its traditional May 30 date to the last Monday in May.
By the early 20th century, Memorial Day was an occasion for more general expressions of memory, as people visited the graves of their deceased relatives in church cemeteries, whether they had served in the military or not. It also became a long weekend increasingly devoted to family gatherings, fireworks, trips to the beach, and national media events. A national moment of remembrance takes place at 3 pm local time. Another tradition is to fly the flag of the United States at half-staff from dawn until noon local time. Volunteers often place American flags on each grave site at national and local cemeteries.
For many Americans, the central event is attending one of the thousands of parades held on Memorial Day in large and small cities all over the country. Most of these feature marching bands and an overall military theme with the National Guard and other servicemen participating along with veterans and military vehicles from various wars. The National Memorial Day Concert takes place on the west lawn of the United States Capitol. The concert is broadcast on PBS and NPR. Music is performed, and respect is paid to the men and women who gave their lives for their country.
