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 contributions of workers to the country's development and achievements

. It originated in the late 19th century as trade unions and labor movements sought a day to celebrate workers' solidarity and advocate for better working conditions

. The first Labor Day parade took place in New York City in 1882, organized by labor unions to demonstrate unity and demand fair working conditions

. The holiday became an official federal holiday in 1894 after widespread state-level recognition

. Labor Day also marks the unofficial end of summer and is often celebrated with parades, speeches, picnics, and other festivities

. Unlike International Workers' Day (May Day), which commemorates labor struggles globally on May 1, Labor Day in the U.S. is specifically tied to the American labor movement and is observed in September

. In summary, Labor Day means a dedicated day to honor the social and economic achievements of American workers, reflect on the history of labor rights, and celebrate the contributions of laborers to society
