UN English Language Day takes place on April 23, 2022. The event was established by the UNESCO in 2010 to 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". April 23 was chosen as the date for the English language because it is the anniversary of William Shakespeare’s death.
English is a West Germanic language that was first spoken in early medieval England and is now a global lingua franca. It is spoken as a first language by the majority populations of several sovereign states, including the United Kingdom, the United States, Canada, Australia, Ireland, New Zealand and a number of Caribbean nations; and it is an official language of almost 60 sovereign states.
English is the third-most-common native language in the world, after Mandarin Chinese and Spanish. It is widely learned as a second language and is an official language of the European Union, many Commonwealth countries and the United Nations, as well as in many world organisations.
