Día de los niños/Día de los libros (Children’s Day/Book Day)

El Día de los Niños/El Día de los Libros, also known simply as Día, is a celebration of children, families, and reading that culminates yearly on April 30. “Children’s Day” has been celebrated in many countries around the world officially since 1925.

After learning about Mexico’s tradition of celebrating April 30th as El Día del Niño, children’s book author Pat Mora helped create a new holiday in the United States emphasizing the importance of literacy for children of all linguistic and cultural backgrounds, linking families to diverse books, languages and cultures.

This page is to help California public libraries plan and support Día celebrations and children and family literacy programs.
