World Day for Cultural Diversity for Dialogue and Development is annually held on May 21 to help people learn about the importance of cultural diversity and harmony.
Various events are organized to increase the understanding of issues around cultural diversity and development among governments, non-governmental organizations and the public. Many of these include presentations on the progress of implementing the Universal Declaration on Cultural Diversity.
The General Conference of the United Nations Educational, Scientific and Cultural Organization (UNESCO) adopted the Universal Declaration on Cultural Diversity in Paris, France, on November 2, 2001. It was the 249th resolution adopted at the 57th session of the United Nations General Conference. Although the declaration was the culmination of years of work, it was adopted in the wake of the terrorist attacks on September 11, 2001. This reaffirmed the need for intercultural dialogue to prevent segregation and fundamentalism.
The year 2002 was the United Nations Year for Cultural Heritage. At the end of that year, on December 20, 2002, the General Assembly of the United Nations declared May 21 to be the World Day for Cultural Diversity for Dialogue and Development. The General Assembly emphasized links between the protection of cultural diversity and the importance of dialogue between civilizations in the modern world. The World Day for Cultural Diversity for Dialogue and Development was first observed in 2003.
