World Book and Copyright Day (also known as International Day of the Book or World Book Day) is observed on April 23rd. The annually celebrated day is organized by UNESCO to promote reading, publishing and copyright. It was first celebrated in 1995.
The connection between 23 April and books was first made in 1923 by booksellers in Spain as a way to honor the author Miguel de Cervantes who died on that day. Nowadays the World Book and Copyright Day is observed in over 100 countries, where schools, private businesses, voluntary organizations and lots of more people and groups come together to pay a tribute to authors and books.
