"Labor Day" - A national legal holiday that is over 100 years old. It grew out of a celebration and parade in honor of the working class by the Knights of Labor in 1882 in New York. In 1884, the Knights held a large parade in New York City celebrating the working class. The parade was held on the first Monday in September. The Knights passed a resolution to hold all future parades on the same day, designated by them as Labor Day.
