World Book Day is a charity event held annually in the United Kingdom and Ireland on the first Thursday in March. It is the local manifestation of World Book and Copyright Day (also known as International Day of the Book or World Book Days) organized by UNESCO to promote reading, publishing and copyright. On World Book Day, every child in full-time education in the UK is given a voucher to be spent on books. The Day was first celebrated in 1995 in the United Kingdom. The original, global World Book Day event is generally observed on 23 April – it was changed in the UK to avoid clashes with Easter school holidays and with St George’s Day. Conversely, a separate event World Book Night organized by independent charity The Reading Agency is held on 23 April.
