In 2001, UNESCO adopted the Universal Declaration on Cultural Diversity and in December 2002, the UN General Assembly, in its resolution 57/249, declared May 21 to be the World Day for Cultural Diversity for Dialogue and Development. Diversity Day, officially known as “The World Day for Cultural Diversity for Dialogue and Development”, is an opportunity to help communities understand the value of cultural diversity and learn how to live together in harmony. It was adopted in the wake of the terrorist attacks on September 11, 2001.
