May Day is a nationwide holiday in Germany. Traditionally, the day has a political connotation in most regions, and is also referred to as "Labor Day". Berlin witnesses yearly demonstrations on May Day, the largest organized by labour unions, political parties and others by the radical left and Autonomen.
The United States has its own Labor Day holiday, celebrated on the first Monday in September instead of on May Day. The U.S. version of Labor Day was a creation of the Knights of Labor, and was adopted officially in 1887 in an effort to disassociate labor activism from the radical left. Subsequent efforts to officially switch Labor Day to the international date of May 1 have failed. In 1958, President Dwight D. Eisenhower proclaimed May 1 both as Loyalty Day and as Law Day.
Despite the prevailing sentiment for observance of Labor Day in September, some unions and union locals in the United States — especially in urban areas with strong support for organized labor — have attempted to maintain a connection with more radical labor traditions through their own unofficial observances on May 1. Some of the largest examples of this occurred during the Great Depression of the 1930s when thousands of leftist workers marched in May Day parades in New York's Union Square.
In New Zealand, Labour Day is a public holiday held on the fourth Monday in October — but the traditions of this October day are borne of International Workers' Day and are not the situation of Canada or the United States.
In Australia, the Labour Day public holiday is fixed by the various states and territories' governments. Depending on the territory in question, the celebrations involved may or may not be connected to International Workers' Day. The day is on the first Monday in October in the Australian Capital Territory, New South Wales and South Australia, while in Western Australia, Labour Day is the first Monday in March, and in both Victoria and Tasmania, it is the second Monday in March (Tasmania calls it "Eight Hours Day"). In both Queensland and the Northern Territory the holiday is on the first Monday in May itself. ("May Day").
In Sweden, Finland, Norway and Iceland, Labour Day is a public holiday, celebrated by many different socialist parties and groups with political demonstrations and speeches. In Sweden and Finland, however, it merges with Walpurgis Night, a carnival-type festivity.
