History of Memorial Day
Memorial Day, as Decoration Day gradually came to be known, originally honored only those lost while fighting in the Civil War. But during World War I the United States found itself embroiled in another major conflict, and the holiday evolved to commemorate American military personnel who died in all wars, including World War II, The Vietnam War, The Korean War and the wars in Iraq and Afghanistan.
For decades, Memorial Day continued to be observed on May 30, the date Logan had selected for the first Decoration Day. But in 1968 Congress passed the Uniform Monday Holiday Act, which established Memorial Day as the last Monday in May in order to create a three-day weekend for federal employees; the change went into effect in 1971. The same law also declared Memorial Day a federal holiday.
Two other days celebrate those who have served or are serving in the U.S. military: Veterans Day, which honors those who have served in the United States Armed Forces;[5] and Armed Forces Day, an unofficial U.S. holiday (earlier in May) for honoring those currently serving in the armed forces.
Many people visit cemeteries and memorials on Memorial Day to honor and mourn those who died while serving in the U.S. Military. Many volunteers place an American flag on graves of military personnel in national cemeteries.
