Junie B. Jones is five years old and starting kindergarten when she appears in her first book, "Junie B. Jones and the Stupid Smelly Bus," written in 1992. As the series of books continues, she eventually becomes six and enters first grade.
The Junie B. Jones series, a group of books popular among young elementary school readers, was written by Barbara Park and contains 29 titles.

My Valentime," which is a book containing original Junie Jones "valentimes" to share with friends. The author died in 2013, meaning that Junie B. Jones always remains six.
