Every person in the world is either directly or indirectly a worker. In most countries around the world, May 1 is celebrated as International Labour Day. In many countries, May 1 is declared a public holiday.

Labour Day is observed especially in communist countries. It is celebrated in Soviet countries, Europe, Britain, and London. Notably, the May Day parade in Moscow is world-famous.
Since 1886, Labour Day has been recognized globally. In 1925, in India, labourers held a procession carrying placards demanding freedom for the country, and from this event, May Day celebrations began. However, Labour Day is not celebrated in countries like the United States, Canada, and Italy.
