World Book Day is an annual event celebrated on the first Thursday in March in the United Kingdom and Ireland. Its purpose is to promote reading, publishing, and copyright. Schools and libraries often organize activities, encouraging children to explore books and engage with stories. On this day, children are encouraged to dress up as their favorite book characters and participate in various reading-related events. Many authors and illustrators also take part by visiting schools and sharing their work. World Book Day aims to inspire a love of reading and make books accessible to all children.
