On April 23 World Book Day is Celebrated - World Book Day or World Book and Copyright Day (also known as International Day of the Book or World Book Days) is a yearly event on April 23rd, organized by the United Nations Educational, Scientific and Cultural Organization (UNESCO), to promote reading, publishing, and copyright. In the United Kingdom, the day is recognized on the first Thursday in March. World Book Day was celebrated for the first time on 23 April 1995.

23 April is a symbolic date in world literature. It is the date on which several prominent authors, William Shakespeare, Miguel Cervantes and Inca Garcilaso de la Vega all died.

World Book and Copyright Day is an occasion to pay a worldwide tribute to books and authors and to encourage people to discover the pleasure of reading. It is hoped that this will lead to the renewed respect for those who have made irreplaceable contributions to social and cultural progress.

It is also hoped that World Book and Copyright Day will increase people's understanding of and adherence to copyright laws and other measures to protect intellectual copyright.

Each year a poster is designed and distributed around the world. It features images designed to encourage people, particularly children, to read books and appreciate literature. There is also a logo for World Book and Copyright Day. It features a circle, representing the world, and two books, one of which is open.
