International Workers' Day, also known as Labour Day in some countries, and often referred to as May Day, is a celebration of labourers and the working classes that is promoted by the international labour movement which occurs every year on May Day (1 May), an ancient European spring festival.

The date was chosen by a pan-national organization of socialist and communist political parties to commemorate the Haymarket affair, which occurred in Chicago on 4 May 1886. The 1904 Sixth Conference of the Second International, called on "all Social Democratic Party organisations and trade unions of all countries to demonstrate energetically on the First of May for the legal establishment of the 8-hour day, for the class demands of the proletariat, and for universal peace."

The first of May is a national public holiday in many countries worldwide, in most cases as "Labour Day", "International Workers' Day" or some similar name - although some countries celebrate a Labour Day on other dates significant to them, such as the United States, which celebrates Labour Day on the first Monday of September.

Beginning in the late 19th century, as the trade union and labour movements grew, a variety of days were chosen by trade unionists as a day to celebrate labour. In the United States and Canada, a September holiday, called Labor or Labour Day, was first proposed in the 1880s. In 1882, Matthew Maguire, a machinist, first proposed a Labor Day holiday on the first Monday of September while serving as secretary of the Central Labor Union (CLU) of New York. Others argue that it was first proposed by Peter J. McGuire of the American Federation of Labor in May 1882, after witnessing the annual labour festival held in Toronto, Canada. 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 U.S. states officially celebrated Labor Day. Thus by 1887 in North America, Labor Day was an established, official holiday but in September, not on 1 May.
