The base has an annular bottom wall (18) with an annular array of upwardly projecting protrusions (20). The schedule indicator also includes a first condition indicating ring (24) and a second condition indicating knob (25) positioned concentrically within the indicating ring. The indicating ring has a peripheral top surface (27) having an annular array of timing indicia (28), a recessed top surface (29) having an annular array of top depressions (31), and a bottom surface (32) with an annular array of bottom depressions (33). The indicating knob has a grasping portion (37) with a second selection arrow (38) thereon, and at least one protrusion (39) sized and shaped to be releasably received within the indicating ring top depressions (31).
