Labor Day is a legal holiday observed in the United States, Canada, Puerto Rico, the Canal Zone, and the Virgin Islands. The celebration of Labor Day, in honor of the working class, was initiated in the U.S. in 1882 by the Knights of Labor, and the first Labor Day holiday was celebrated on Tuesday, September 5, 1882, in New York City, in accordance with the plans of the Central Labor Union. The Central Labor Union held its second Labor Day holiday just a year later, on September 5, l883.

In l884 the first Monday in September was selected as the holiday, as originally proposed, and the Central Labor Union urged similar organizations in other cities to follow the example of New York and celebrate a "workingmen's holiday" on that date. The idea spread with the growth of labor organizations, and in l885 Labor Day was celebrated in many industrial centers of the country.
