1 May is observed as a International Labour Day (also known as May Day or International Workers’ Day) every year across the world. The day celebrates the struggle, dedication and commitment of the working class and is an annual public holiday in several countries.


On 1st May in 1886, Chicago and a few other cities were the sites of a major union demonstration in support of the eight-hour workday demand. In the year 1889, the International Socialist Conference declared that in commemoration of the Haymarket affair, 1 May would be an international holiday for the labour force, now known as International Workers’ Day.
