World Metropolitan Day

World Metropolitan Day is observed every year on October 14th.

It was previously celebrated on October 7, but the date was changed to align with global urban and sustainability events.

The day highlights the importance of metropolitan governance and regional cooperation in addressing urban challenges.

It is organized by Metropolis (World Association of Major Metropolises) in partnership with UN-Habitat.

The observance supports Sustainable Development Goal 11 — to make cities inclusive, safe, resilient, and sustainable.
