On May 1st, many countries around the world celebrate International Labor Day (Spring and Labor Festival), which was originally known as International Workers' Solidarity Day. On May 1st, 1886, American workers organized a strike in Chicago, demanding an 8-hour work day. The strike and ensuing demonstration ended in a bloody confrontation with the police. In July 1889, the Paris Congress of the Second International, in memory of the workers' uprising, decided to hold annual demonstrations on May 1st. The first International Workers' Solidarity Day was celebrated in 1890 in Austria-Hungary, Belgium, Germany, Denmark, Spain, Italy, the USA, Norway, France, Sweden, and several other countries. For a long time, May Day was a symbol of revolution, irreconcilable class struggle, had a "political color," and was celebrated with demonstrations adorned with portraits of political leaders, production pioneers, slogans, calls, posters, and diagrams about achievements in various sectors of the national economy, science, and culture. However, this context gradually faded. Today, the holiday is celebrated in more than 140 countries and territories around the world on May 1st or the first Monday of May. In some countries, the tradition of gathering people under the banners of unions still persists, but in most states, it is no longer a political holiday, but rather Labor Day, a bright spring festival, where folk celebrations, artistic performances, fairs, peaceful marches, and numerous entertaining activities are organized. For some, it is just another day off to relax or spend time with family. Additionally, in some countries, Labor Day is celebrated at a different time – including, for example, the USA and Japan. In more than 80 countries (including India), Labor Day is not celebrated.
