Celebrating May 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.
In the late 19th century, May Day was chosen as the date for International Workers' Day by the Socialists and Communistsof the Second International to commemorate the Haymarket affair in Chicago. In those countries that celebrate International Workers' Day, the day may also be referred to as "May Day" but it is a different celebration from the traditional May Day.
