A model is proposed where, in addition to the previously established human behavioral patterns tracked to the annual sunlight-driven dopamine cycle or seasonal pattern, a second dopamine “clock” is proposed in the human brain. This clock-cycle involves a wavelength of 40.5 days (approximately 1/9th of a 365 day calendar year) starting at the winter solstice on December 21. This cycle is measured in this proposal starting with a 13 to 14 day-long concave dopamine peak with hyperactive and impulsive temperament, diminishing to a 13 to 14 day-long period of calm and focus, and ending with a 13 to 14 day-long convex phase with increased anxiety and depression, after which the cycle begins again. These two cycles are considered as the only factors needed to map an aggregate annual calendar of human temperament.
