The first recorded celebration of the founding of Madras was its tercentenary commemoration in 1939. Unlike later anniversaries, the celebrations were officially sponsored by the British government and a special tercentenary commemoration volume was issued with essays on the different aspects of Madras city authored by leading experts of the time. An exhibition of pictures, portraits, maps, records and coins was inaugurated by

Madras University and a short play writing competition was organised. The 350th anniversary in 1989 was celebrated with the opening of a commemorative monument titled "Madras 350" built in the Classical Style by builder Frankpet Fernandez at the junction of the
Poonamallee High Road and the New Avadi Road. Other major events included the commissioning of a book by S. Muthiah titled
Madras — The Gracious City by the
Murugappa Group which also organised the first Madras Quiz which has continued to the present day. It was based on the success of another event called Mylapore Festival which D'Souza had been organising every year in January. It was decided by the trio to start celebrating Madras Day from 2004. The idea initially started off with about five events in 2004 but grew gradually. The second edition in 2005 had events throughout the week. In 2008, there were a total of 60 events conducted. The 2010 celebrations lasted beyond a week and extended well into the following week as well. The 375th Madras Day was celebrated with more than a hundred events that lasted from 10 August to 14 September 2014. "
