May Day

People in different  places  celebrate May day  specially   its  holiday for all workers 
almost  all countries celebrate May day  Asian and European countries  gave national holiday  on that day  
May Day occurs on May 1 and refers to several public holidays. In many countries, May Day is synonymous with International Workers' Day, or Labour Day, a day of political demonstrations and celebrations organised by unions, communists, anarchists, socialists, and activist groups. May Day is also a traditional holiday in many cultures.
The idea for a "workers holiday" began in Australia in 1856; after a Stonemason's victory, April 22nd was "Eight-Hour Day", a public holiday. With the idea having spread around the world, the choice of May 1st became a commemoration by the Second International for the people involved in the 1886 Haymarket affair
May Day has become an international celebration of the social and economic achievements of the labour movement. Although the commemoration of May Day as International Workers' Day received its inspiration from the United States, the U.S. Congress designated May 1 as Loyalty Day in 1958 due to the day's perceived appropriation by the Soviet Union
Alternatively, Labor Day traditionally occurs on the first Monday in September in the United States. People often use May Day as a day for political protest, such as the million people who demonstrated against far-right candidate Jean-Marie Le Pen in France, or as a day for protest against government actions, such as rallies in support of undocumented workers across the United States
