About Día

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

Día is an enhancement of Children’s Day, which began in 1925.  Children’s Day was designated as a day to bring attention to the importance and well-being of children.  In 1996, nationally acclaimed children’s book author Pat Mora proposed linking the celebration of childhood and children with literacy to found El día de los niños/El día de los libros.


Through a series of grants from the W. K. Kellogg Foundation, the Association for Library Service for Children (ALSC) continues to increase public awareness of the event in libraries throughout the country. ALSC is collaborating on this effort with the Founding Partner of Día, the National Association to Promote Library and Information Services to Latinos and the Spanish Speaking (REFORMA). In 2007, ALSC welcomed Target as the first official national sponsor of Día.

We hope you'll take a few minutes to explore the resources available here, including information about educational programs, a list of our generous sponsors, free materials including a downloadable PSA by Día founder Pat Mora and Celebrate!/Celebremos brochures in English and Spanish (available in PDF), and more.
