The 1st of May as the Workers’ Solidarity Day began to be celebrated in Lviv simultaneously with the cities of Western Europe and America: in 1890. This date was determined by the congress of the Second International in memory of the mass protests of workers for the 8-hour working day, which took place in the USA in 1886. Before, the pagan feast of the "return of spring" was celebrated in Lviv, as in many parts of the continent, on this day. Traditionally, a military chapel choir held a so-called "awakening" on the streets of the city center, which was actually dedicated to "the first day of May." From 1890, the emphasis changed.
