This disclosure describes techniques implemented by a medical device, such as an implantable medical device (IMD). The IMD may be configured to detect a posture state of a patient, and deliver posture-responsive therapy. In particular, the IMD not only detects the posture state of a patient, but also detects timing associated with the detected posture state, such as the time of day, the day of the week, or a specific time of day associated with a specific day. In this way, the posture-responsive therapy delivered by the IMD may be dependent not only on the posture state of the patient, but also on the timing associated with the posture state. The same posture state, therefore, may result in different types of therapy to the patient if the same posture occurs at different times of the day.
