Why do they do May Day?

May Day, celebrated on May 1st, is primarily a celebration of workers and their rights, originating from the labor movement in the late 19th century. It commemorates the struggle for better working conditions, fair wages, and the eight-hour workday, significantly marked by events like the Haymarket affair in Chicago. Beyond labor rights, May Day is also associated with springtime festivals in various cultures, symbolizing renewal and fertility. Today, it serves as a platform for advocating social justice and workers' rights globally.
