International Labour Day (May Day), May 1
International Workers' Day, also known as Labour Day but also referred to as May Day in most countries is a celebration of laborers and workers in our society. 1 May was chosen to be International Workers' Day to commemorate the 1886 Haymarket affair in Chicago. In that year beginning on 1 May, there was a general strike for the eight-hour workday. It became a yearly commemoration, inspiring American workers to have their first stoppage. Mayday is a public holiday, so don't forget to relax, have fun and unwind.
