May Day, Workers Day!

May Day on May 1 is an ancient Northern Hemisphere spring festival and usually a public holiday; it is also a traditional spring holiday in many cultures. Dances, singing, and cake are usually part of the celebrations that the day includes.

Traditional English May Day rites and celebrations includeMorris dancing, crowning a May Queen and celebrations involving a maypole. Much of this tradition derives from the pagan Anglo-Saxon customs held during "Þrimilci-mōnaþ", (the Old English name for the month of May meaning Month of Three Milkings) along with many Celtic traditions.

International Workers' Day, also known as Labour Day in some places, is a celebration of laborers and the working classes that is promoted by the international labor movement, anarchists, socialists, and communists and occurs every year on May Day, 1 May, an ancient European spring holiday... The date was chosen for International Workers' Day by the Second International to commemorate the Haymarket affair, which occurred in Chicago on 4 May 1886. This Day has its origins in the labour union movement, specifically the eight-hour day movement, which advocated eight hours for work, eight hours for recreation, and eight hours for rest
