Labor Day is a United States federal holiday observed on the first Monday in September that celebrates the economic and social contributions of workers.
The first big Labor Day in the United States was observed on September 5, 1882, by the Central Labor Union of New York. It was first proposed by Peter J. McGuire of the American Federation of Labor in May 1882, after witnessing the annual labor festival held in Toronto, Canada.
