Labor Day in the United States is a public holiday celebrated on the first Monday in September. It honors the American labor movement and the contributions that workers have made to the strength, prosperity, laws and well-being of the country.
In the United States and Canada, however, the official holiday for workers is Labor Day in September. After the Haymarket Square riot in May, 1886, US President Grover Cleveland feared that commemorating Labor Day on May 1 could become an opportunity to commemorate the riots.
