May 1 / Labour Day

The celebration of Labour Day has its origins in the eight hour day movement, which advocated eight hours for work, eight hours for recreation, and eight hours for rest. On 21 April 1856 Stonemasons and building workers on building sites around Melbourne, Australia, stopped work and marched from the University of Melbourne to Parliament House to achieve an eight hour day.
