Overview

World Basketball Day is observed on 21 December. The United Nations General Assembly proclaimed the day through resolution A/RES/77/324 in 2023, making basketball the first team sport to receive a dedicated UN international day.

The observance uses basketball as a platform for participation, inclusion, community connection and sport for development and peace. Those outcomes are not automatic: access, safety, disability inclusion, gender equity and fair opportunities to participate still depend on how programmes are designed.

Why it matters

Basketball is played in many settings—from informal local courts to schools, clubs and international competition—and can create shared activity across language, cultural and social differences.

A strong observance can celebrate the game while also asking practical questions about who has access to courts, coaching, equipment and safe participation, and how sport programmes can support rather than merely claim inclusion.

History

Basketball was first played on 21 December 1891 at the International YMCA Training School in Springfield, Massachusetts, after James Naismith developed the game.

Indonesia, Nicaragua, Peru and the Philippines were the initial sponsors of draft resolution A/77/L.95, and the Philippines introduced the draft in the General Assembly.

On 25 August 2023, the General Assembly adopted resolution A/RES/77/324 and proclaimed 21 December World Basketball Day. United Nations and FIBA material identify 21 December 2023 as the inaugural observance.

Ways to observe

01

Run an inclusive pickup session with clear rotation rules so beginners and experienced players both receive meaningful playing time.

02

Explore basketball history through the original 1891 game, the growth of women’s basketball, adaptive and wheelchair basketball, and the sport’s development in different regions.

03

Use a school or club session to identify barriers to participation such as court access, equipment cost, unsafe facilities, discriminatory behaviour or lack of suitable coaching.

04

Connect a basketball activity to a concrete community purpose—youth mentoring, disability inclusion, intercultural exchange or safe recreation—and evaluate whether the activity actually reaches the intended group.
