UN Spanish Language Day is celebrated on October 21, 2016. The day, which is observed annually, was created by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 2010, as part of the establishment of several United Nations language days. It is also called Día de la Raza or Día de la Hispanidad.
UN Spanish Language Day aims to celebrate multilingualism and cultural diversity. The language days in general also should promote equal use of all six official working languages throughout the organization. The date was chosen, as October 12 is Spain's National Day and both days were wanted to coincide. Spanish is not only one of the official languages of the United Nations, but a language with more than 470 million native speakers. Some countries also celebrate October 12 as Day of the Race.
