Collection note, 15/09/2026 Día: children, books and April 30

1. What is Día and why do libraries celebrate children and books on April 30?

Día is an annual celebration of children, books and cultures. It is held on April 30, and it is built around a simple pairing: every child should have a book, and every book should have a reader. The name comes from Spanish, and the celebration keeps the Spanish terms because that is how it is known in libraries and schools.

The date is not arbitrary. April 30 is Children's Day in Mexico, where it has been celebrated since 1925. Pat Mora's contribution, in 1996, was to propose that the same day also honor books and reading. The first celebrations followed in 1997.

Libraries celebrate Día for reasons that are practical as well as symbolic. A library that marks the day is doing several things at once: it invites families who may not use the library regularly, it puts books in many languages on display, and it gives children a chance to see their own cultures reflected in what they read. The celebration is not a contest and not a single event. It is a date that a library, a school or a community room can fill with story times, crafts and read-alouds.

2. Who started El día de los niños / El día de los libros and how did it spread since 1997?

The idea belongs to Pat Mora, a writer who proposed in 1996 that Children's Day be linked to books. The first Día celebrations were held in 1997. From there the celebration spread through libraries, schools and community organizations, and the American Library Association took on national sponsorship, which gave the date a shared name and a shared set of materials.

The growth was not a single campaign. It moved through the people who already worked with children and books: public and school librarians, bilingual and dual-language teachers, reading specialists, and volunteers who run story times. Each group adapted the day to its own setting. A large library system might hold a full afternoon of programming. A small school might set aside one class period for read-alouds. A community room might host a book swap.

The Texas Library Association, REFORMA and the American Library Association are among the institutions associated with the celebration, and Pat Mora is its named originator. In the years since 1997, Día has also become a date for talking about which books children are given: bilingual English-Spanish editions, Own Voices titles, and picture books that reflect many cultures and languages.

3. How is Children's Day celebrated in Mexico on April 30 and what does it mean for families?

In Mexico, April 30 is Children's Day, and it has been observed on that date since 1925. Schools and families mark it in ways that vary by place, but the day is generally about children themselves: attention paid to them, time spent with them, and small gifts or activities organized around them.

For families, the date carries a meaning that is easy to state and hard to measure. It is a day when a child is the reason for the gathering. When Día adds books to that day, the two ideas sit together: the child is honored, and the child is handed a book. Families who read in two languages often use the date to keep both languages in use at home, reading aloud in English and Spanish in the same sitting.

4. What does Día look like in a library or a classroom?

A Día event does not require a large budget. The common elements are a space, a reader and a set of books. Story times are the center of most programs. Around them, libraries and schools add crafts, book displays, and partner organizations that bring their own audiences.

Multicultural and bilingual books are usually the point of the display table. The titles chosen tend to include bilingual English-Spanish editions, Own Voices books, picture books for toddlers through middle grade, and read-aloud choices that work for a mixed audience of children and adults. The test is not whether a book is new. The test is whether a child in the room can find themselves in it.

Programs also vary by age. A teen title and a board book do not serve the same reader, and a Día program that tries to cover every age in one hour usually serves none of them well. Librarians who plan the day often split it into blocks: toddlers first, then middle grade, then a family read-aloud at the end.

5. How do families keep the day going after April 30?

The celebration is one date, but the practice is daily. Families who want to carry Día past April 30 usually do three things: they read aloud at home, they keep books where children can reach them, and they read in both languages if both are spoken in the house.

Reading aloud in two languages is not a performance. It can be one book in English and one in Spanish, or the same book read twice. The point is that the child hears both languages used for pleasure, not only for instruction. Bilingual habits survive when they are attached to something enjoyable, and a story read at bedtime is enjoyable in a way that a vocabulary list is not.

Summer is the hard part. School reading routines end, and library visits drop. Families who keep a small stack of books visible, and who return to the library on a fixed day each week, tend to keep the habit. Día itself returns on April 30, and libraries that mark it often start planning weeks earlier, which gives families a date to look forward to.

6. What a reader can check

The facts above rest on public sources. The date of Children's Day in Mexico, April 30, goes back to 1925. Pat Mora proposed linking the date to books in 1996. The first Día celebrations were held in 1997. The American Library Association holds national sponsorship. The Texas Library Association and REFORMA are among the institutions associated with the celebration. Readers who want the history in more detail, or who want to plan an event, can start with the ALA Día site and with the state library associations, which publish program guides and book lists.

The date is the same every year. What changes is how many children in how many places are handed a book on that day.
