The happy idea of using a proletarian holiday celebration as a means to attain the eight-hour day was first born in Australia. The workers there decided in 1856 to organize a day of complete stoppage together with meetings and entertainment as a demonstration in favor of the eight-hour day. The day of this celebration was to be April 21. At first, the Australian workers intended this only for the year 1856. But this first celebration had such a strong effect on the proletarian masses of Australia, enlivening them and leading to new agitation, that it was decided to repeat the celebration every year.
