Final answer:
Labor Day in the United States is celebrated on the first Monday in September, honoring workers' contributions, and is associated with the end of summer and the labor movement's legacy.
Step-by-step explanation:
In the United States, Labor Day is celebrated on the first Monday of September each year. This holiday honors the contributions of American workers and the labor movement's history of advocating for workers' rights. Although the origins of Labor Day trace back to significant events in the labor movement during the 1880s, such as the push for an eight-hour workday, today it represents a time for relaxation and signifies the unofficial end of summer.
This day off also allows workers to enjoy a three-day weekend, as the idea of a two-day weekend was an achievement of the labor movement. While May Day, or International Workers' Day, is celebrated on May 1 in many countries as a day of labor solidarity in remembrance of the Haymarket affair and the fight for the eight-hour workday, in the U.S., the Labor Day holiday was officially established as a federal holiday in 1894 and is distinct from May Day celebrations.
