Restless legs syndrome (RLS) is characterized by unpleasant sensations in the limbs, usually the legs, that occur at rest or before sleep and are relieved by activity such as walking. These sensations are felt deep within the legs and are described as creeping, crawling, aching, or fidgety.
In North America, autumn is usually considered to start with the September equinox (21 to 24 September) and end with the winter solstice (21 or 22 December).
Technically, in a calendrical sense, North American seasons are counted by the equinoxes and solstice, cutting the year neatly into four three-month segments: 1  in 2016, winter is officially 22 Dec 2015-20 Mar 2016. 2  Spring will be 20 Mar-20 June. 3  Summer will be 20 June-22 Sept.  Fall will be 22 Sept-21 Dec.
