From Pat’s History of Día: April 2016 is Día’s 20th anniversary. In 1996, while being interviewed for a public radio program at the University of Arizona in Tucson, I first learned about the annual Mexican tradition of celebrating April 30th as El día del niño, the Day of the Child. As a mom I knew that children often ask, “Why do we have Mother’s Day and Father’s Day and not Children’s Day?” As a reader, I wanted (and want) to foster bookjoy. Ah ha, I thought. What if we link a celebration of children with literacy, an issue central to the well-being of children? Read more, and enjoy our visual history.
