WORLD BOOK DAY is a yearly event on 23 April, organized by UNESCO to promote reading, publishing and copyright. The Day was first celebrated in 1995 and in 2012 the UK World Book day was celebrated on March 1, 2012.
World Book Day was celebrated for the first time on April 23. The connection between 23 April and books was first made in 1923 by booksellers in Spain as a way to honour the author Miguel de Cervantes who died on that day.
In 1995, UNESCO decided that the World Book and Copyright Day would be celebrated on this date because of the Catalonian festival and because the date is also the anniversary of the birth and death of William Shakespeare, the death of Miguel de Cervantes, Inca Garcilaso de la Vega and Josep Pla, and the birth of Maurice Druon, Manuel Mejía Vallejo and Halldór Laxness.
