Memorial day is observed on the last Monday of May and was established during the Civil War. Memorial Day honors those who have died in military service for the U.S. In recent history, Memorial Day has meant the unofficial start to summer.
Memorial day is celebrated all throughout the U.S with parades and many visit the graves/ memorials of their loved ones putting flags and flowers there for them. In 1971, Memorial Day was declared a national holiday by an act of Congress, though it is still often called Decoration Day. This year, memorial day is on Monday May 27.
