In many countries around the world, May 1 is observed as International Workers’ Day or International Labor Day. In the United States, it is known as May Day, while the country’s Labor Day falls in September.

May 1 is a national holiday in several countries. It originated in the 19th century when trade unions and labor movements were on the rise along with several industries. May 1 was selected as International Workers’ Day to commemorate the Haymarket affair in Chicago on May 4, 1886, when police was working to control protesters during labor strike. An unidentified person hurled a bomb at the police, who in turn opened fire on the workers, leaving four civilians dead.
