The UN Department of Public Information launched English Language Day in 2010 as part of an initiative celebrating the organization's six official languages. April 23 was chosen because it traditionally marks both the birth and death of English playwright William Shakespeare, giving the day a special symbolic connection to one of the greatest figures in the history of the English language. The day celebrates multilingualism within the United Nations and deepens understanding of the history, evolution, and rich dialectal diversity of English, one of the most widely used languages in international communication, science, trade, and diplomacy. It also highlights the contributions of English literature, from Shakespeare's plays to modern literary works. UN offices and cultural centers worldwide mark the occasion with literary and theatrical evenings inspired by Shakespeare's works, creative writing competitions, and educational events encouraging people to learn English.
