The international organisation for "World Urbanism Day" or "World Town Planning Day" was founded by Carlos Maria della Paolera (1890-1960), professor at University of Buenos Aires, in 1949 aiming to advance both public and professional interest in planning, to promote the role of planning in creating livable communities. The day is celebrated in more than 30 countries on 8th of November each year (via).
This year, there is no theme. In 2014, the theme was "Equality in the Cities - Making Cities Socially Cohesive" (see abstracts).
