April 23 is observed as UN English Language Day, every year. The day was established by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 2010 to celebrate the English language and multilingualism.
English Language Day marks the birthday and date of death of famed writer William Shakespeare.
The United Nations welcomed the creation of International Mother Earth Day, saying: "International Mother Earth Day promotes a view of the Earth as the entity that sustains all living things found in nature. Inclusiveness is at the heart of International Mother Earth Day; fostering shared responsibilities to rebuild our troubled relationship with nature is a cause that is uniting people around the world."
