World Habitat Day is held on the first Monday of October each year and launches Urban October. The day centers around the global observance, which is held in a different country each year with keynote speakers and roundtable discussions focused on a specific theme. World Habitat Day was first celebrated in 1986 in Nairobi, Kenya, with the theme ‘Shelter is my right’.

On 5 October 2026, the Global Observance of World Habitat Day will be related to "Adequate Housing for All". The global housing crisis whereby an estimated 2.8 billion people face various forms of housing inadequacy, in which close to 1.1 billion reside in slums and informal settlements, calls for urgent and concerted action. World Habitat Day will consider how to realize the ambition of ensuring access to adequate housing for all as a cornerstone for achieving the SDGs and the New Urban Agenda.
