Memorial Day is observed on the last Monday of May. It was formerly known as Decoration Day and commemorates all men and women who have died in military service for the United States. Many people visit cemeteries and memorials on Memorial Day and it is traditionally seen as the start of the summer season.
Memorial Day is a federal holiday. All non-essential Government offices are closed, as are schools, businesses, and other organizations. Memorial Day started as an event to honor Union soldiers who had died during the American Civil War. It was inspired by the way people in the Southern states honored their dead. After World War I, it was extended to include all men and women who died in any war or military action.
