Human Rights Day, international day of observance, held annually on December 10, in commemoration of the anniversary of the adoption of the Universal Declaration of Human Rights (UDHR). The UDHR is a milestone document, which proclaims the inalienable rights that everyone is entitled to as a human being – regardless of race, color, religion, sex, language, political or other opinion, national or social origin, property, birth or other status. The Office of the United Nations High Commissioner for Human Rights plays a prominent role in coordinating worldwide efforts to celebrate the day, which routinely features cultural events and performances, public meetings and seminars, and other educational activities in promotion of human rights.
