Which annual international observance is held on Hans Christian Andersen’s birthday?

International Children’s Book Day is held on Hans Christian Andersen’s birthday, 2 April.

The observance was established in 1967 by the International Board on Books for Young People, commonly known as IBBY. It promotes children’s books and reading around the world, and the date was chosen to honor Andersen’s lasting influence on children’s literature.

Each year, a different national section of IBBY sponsors the event and selects a writer or illustrator to create a message and artwork. These materials are distributed internationally to celebrate books for young readers and encourage interest in literature.

International Children’s Book Day is distinct from World Book Day, which is observed on different dates depending on the country. Its fixed connection with Andersen’s birthday makes it an especially direct tribute to the Danish author.
