Which day is recognized as Labor Day in the United States?

Labor Day in the United States is recognized as the first Monday in September. This holiday was established to honor and recognize the contributions of American workers and the labor movement. It serves as a celebration of the achievements of workers, reflecting the importance of labor in the development of the nation.

The selection of September aligns with the end of summer and serves as a time for families to come together, often marking it as a significant weekend for barbecues, community events, and outdoor activities. The establishment of Labor Day as a national holiday recognized the need for workers' rights and the social and economic advancements that labor movements have achieved over time.

The other options represent different holidays or observances: the last Monday in May is observed as Memorial Day, the second Tuesday in November is known for elections, and the first Tuesday in December does not correspond to a widely recognized holiday in the U.S. Thus, the correct identification of Labor Day highlights the importance of labor rights and the historical context surrounding the celebration of American workers.
