Although the Colombian Constitution specifies Spanish (Castellano) as the official language in all Colombian territory, other languages spoken in the country by ethnic groups – approximately 68 languages – each is also official in its own territory. English is also official in the archipelago of San Andrés, Providencia and Santa Catalina.
The official Colombian time is controlled and coordinated by the National Institute of Metrology.
Colombia is one of the most ethnically and linguistically diverse countries in the world, with its rich cultural heritage reflecting influences by indigenous peoples, European settlement, forced African migration, immigration from Europe and the Middle East. Urban centres are mostly located in the highlands of the Andes mountains and the Caribbean coast.
The name "Colombia" is derived from the last name of Christopher Columbus (Italian: Cristoforo Colombo, Spanish: Cristóbal Colón). It was conceived by the Venezuelan revolutionary Francisco de Miranda as a reference to all the New World, but especially to those portions under Spanish rule (by then from Mississippi river to Patagonia). The name was later adopted by the Republic of Colombia of 1819, formed from the territories of the old Viceroyalty of New Granada (modern-day Colombia, Panama, Venezuela, Ecuador, and northwest Brazil).
