UN Spanish Language Day is observed annually on 23 April. The event was established by the UN's Department of Public Information in 2010, seeking "to celebrate multilingualism and cultural diversity as well as to promote equal use of all six of its official working languages throughout the organization". The day was firstly observed on 12 October to celebrate the Día de la Hispanidad in some Spanish-speaking countries for the discovery of American continent. Later, the day was changed to 23 April, to pay tribute to Spanish writer Miguel de Cervantes Saavedra, who died on 22 April 1616.
