#BlueStarByte: Why Does the U.S. Celebrate Labor Day in September?

While the world celebrates International Workers’ Day on May 1, the United States observes Labor Day on the first Monday of September. The tradition dates back to September 5, 1882, when the Central Labor Union organized a march through New York City, with about 10,000 workers advocating for better working conditions. In the years that followed, labor organizations across the United States began celebrating Labor Day in September as a way to recognize workers.

In 1889, the International Socialist Congress in Paris designated May 1 as a day to promote the eight-hour workday, establishing the date as an International Workers’ Day. Given May Day’s association with socialist and communist movements, the U.S. maintained its own September tradition. In June 1894, amid growing labor tensions and the nationwide Pullman Strike, President Grover Cleveland signed legislation making the first Monday in September a federal holiday, cementing the American tradition of celebrating Labor Day separately from May Day.
