Beginning in the late 19th century, as the trade union and labor movements grew, trade unionists proposed that a day be set aside to celebrate labor. “Labor Day” was promoted by the Central Labor Union and the Knights of Labor, which organized the first parade in New York City. In 1887, Oregon was the first state of the United States to make it an official public holiday. By the time it became an official federal holiday in 1894, thirty states in the U.S. officially celebrated Labor Day.
Canada’s Labour Day is also celebrated on the first Monday of September. More than 80 countries celebrate International Workers’ Day on May 1, the ancient European holiday of May Day. May Day was chosen by the Second International of socialist and communist parties to commemorate the Haymarket affair, which occurred in Chicago on May 4, 1886.
In the United States, many school districts resume classes around the Labor Day holiday weekend (see First day of school). Some begin the week before, making Labor Day weekend the first three-day weekend of the school calendar, while others return the Tuesday following Labor Day. Many districts across the Midwest are opting to begin school after Labor Day.
There are numerous events and activities organized in major cities. For example, New York offers the Labor Day Carnival, and fireworks over Coney Island. In Washington, one popular event is the Labor Day Concert at the U.S. Capitol featuring the National Symphony Orchestra with free attendance.
