Labor Day is a federal holiday in the United States celebrated on the first Monday of September to honor and recognize the American labor movement and the works and contributions of laborers to the development and achievements in the United States.
In 1894, thirty U.S. states were already officially celebrating Labor Day. That year, Congress passed a bill recognizing the first Monday of September as Labor Day and making it an official federal holiday. President Grover Cleveland signed the bill into law on June 28.
