The journal has three months of daily journaling pages and a section at the front they can fill out at any time. Children are encouraged to fill out their journal every day but as the pages aren't dated it is possible to do it at your own rhythm and easy to keep going should you miss a day.
Three months is an ideal length as it's similar to a school term and so feels achievable for the children to establish their new daily journaling habit. When testing the kids preferred this length and a longer book would have been too bulky or heavy for small hands.
Continuation editions will be coming soon but for now children are repeating the same journal on completion which is a nice way to reinforce the gratitude practice and growth mindset principles.
