Mecha is closed Monday, May 29th for Memorial Day.
Memorial Day was originally called Decoration Day. Decoration Day began during the American Civil War when citizens placed flowers on the graves of those who had been killed in battle. After World War I, it was extended to include all men and women who died while in service to the United States during any war or military action. After World War II, the holiday became more commonly referred to as Memorial Day.
Decoration Day and then Memorial Day used to be held on May 30, regardless of the day of the week. In 1968, the Uniform Holidays Bill was passed as part of a move to use federal holidays to create three-day weekends. This meant that from 1971, Memorial Day has been officially observed on the last Monday in May.
Memorial Day is considered a federal holiday. All non-essential Government offices are closed, as are schools, many businesses, and other organizations. Many people see Memorial Day weekend as an opportunity to go on a short vacation or visit family or friends, often celebrating with outdoor cookouts. Memorial Day is now unofficially seen as the start of the summer season.
It is traditional to fly the flag of the United States at half staff from dawn until noon. Many people visit cemeteries and memorials, particularly to honor those who have died in military service. Many volunteers place an American flag on each grave in national cemeteries.
