Labor Day is a United States federal holiday observed on the first Monday in September celebrating the economic and social contributions of workers.

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, 1883.

In 1884 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 1885 Labor Day was celebrated in many industrial centers of the country.

It was first nationally recognized in 1894 to placate unionists following the Pullman Strike. With the decline in union membership, the holiday is generally viewed as a time for barbecues and the end of summer vacations – and time for the first long weekend for schools in Fairfax County.
