Abstract: Much work has been done to investigate social jetlag, a misalignment between the biological clock and the social agenda, related to exposition to dirent light inputs, that causes several health issues. To investigate synchronization and attractors due to a sequence of light inputs, we introduce an extension of a model, previously used to describe jetlag caused by a single change in the light input. The synchronization to the light input is sensitive to the control parameters of the system and to the light input periods. Depending on the parameter set, the observed synchronization is with one or another successive light input. Most of the solutions have the period of the light input. However, for some parameters, we also observe higher period, chaotic solutions, and bistability.
