The international organisation for World Urbanism Day, also known as "World Town Planning Day", was founded in 1949 by the late Professor Carlos Maria della Paolera of the University of Buenos Aires, a graduate at the Institut d'urbanisme in Paris, to advance public and professional interest in planning. It is celebrated in more than 30 countries on four continents each November 8.
