This authority record treats the observance as a fixed annual date. The same month and day can be reused unless a stronger source changes the rule. Public-holiday or government status is never inferred from the observance name alone.
Overview
World Cities Day is observed on 31 October to promote international interest in urbanization and cooperation on sustainable urban development.
The day sits within the wider Urban October period and gives cities, governments, communities and institutions a recurring point for discussing how urban growth, inclusion, services, resilience and planning affect daily life.
Why it matters
Cities concentrate people, infrastructure, opportunity and risk. The observance is therefore useful for examining housing, public space, mobility, climate resilience, services, inequality and local governance together rather than as isolated issues.
Annual host cities and focus topics change. They should be refreshed separately from the permanent 31 October observance and its institutional history.
History

In 2013, the UN General Assembly designated 31 October, beginning in 2014, as World Cities Day. The first global celebration took place in Shanghai on 31 October 2014.
