Abstract: A behavioral calendar structure is arranged to include a support plate mounting an upper housing and lower housing thereto. The upper housing includes a first"W" shaped loop to accommodate one counting sphere for each day per week. A second inverted "U" shaped loop mounted to the second housing includes second spheres to accommodate four more spheres to indicate a corresponding number of misbehaviors of a number of days per week. A total of four more displacements of the second spheres effects the displacement in a week of one of a third sphere of a third loop to indicate a single week's behavior. Misbehavior of three or more such spheres effects displacement of the "W" shaped spheres to indicate in a calendar year the number of months of misbehavioral activity.
