To celebrate International Workers' Day, also known as May Day, Google has honoured workers across the world with a doodle in its homepage.

May 1 is a national holiday in more than 80 countries and celebrated unofficially in many other countries.

First May Day celebration in India was organised in Madras by the Labour Kisan Party of Hindustan on 1 May 1923. This was also the first time the red flag was used in India.

May Day is a nationwide bank and public holiday in India. The holiday is tied to labour movements for communist and socialist political parties. In Maharashtra and Gujarat, it is officially called Maharashtra Day (Maharashtra Din) and Gujarat Day respectively, since on this day in 1960 each attained statehood, after the old Bombay State became divided on linguistic lines.

In many countries, the working classes sought to make May Day an official holiday, and their efforts largely succeeded. The day has long been a focal point for demonstrations by various socialist, communist and anarchist groups..
