International Children's Book Day Date in the current year: April 2, 2024

IBBY is a non-profit organization committed to bringing books and children together. It was founded in Switzerland, but now it has National Sections in many countries from Afghanistan to Zimbabwe.

IBBY established International Children's Book Day (ICBD) in 1967, and it has been celebrated annually ever since. This observance focuses on calling attention to children's books and inspiring a love to reading. Each year a different National Section gets the opportunity to be the international sponsor of the event.

The host country chooses a theme and invites a well-known author and a prominent illustrator to write a message and to design a poster, respectively. The message and the poster are used for promotion of books and reading. Special activities dedicated to ICBD are held in schools and libraries throughout the world. They include writing competitions, meeting with children's book authors and illustrators, awarding ceremonies, and other events.
