El día de los niños/El día de los libros (Children's Day/Book Day), commonly known as Día, is a celebration of children, families, and reading that culminates yearly on April 30. The celebration emphasizes the importance of literacy for children of all linguistic and cultural backgrounds. 

Día is a nationally recognized initiative that emphasizes the importance of literacy for all children from all backgrounds. It is a commitment to linking children and their families to diverse books, languages and cultures.

The common goals of all Día programming are to: 
 Celebrate children and connect them to the world of learning through books, stories and libraries. 

 Nurture cognitive and literacy development in ways that honor and embrace a child’s home language and culture. 

Introduce families to community resources that provide opportunities for learning through multiple literacies. 
 Recognize and respect culture, heritage and language as powerful tools for strengthening families and communities.
