Methods, devices, and systems for monitoring a number of recurrent activities of an individual are disclosed. One method for monitoring a recurrent activity of an individual using activity windowing includes recording a number of sensor activations of at least one sensor, determining a number of peaks in the number of sensor activations, defining one or more time frames based upon the location of at least one of the number of peaks in the time period, and applying a rule associated with a threshold number of activations, where the rule is applied to at least one particular time frame in order to determine whether to initiate an action.
