Seasons divide the year into four distinct periods of time named Spring, Summer, Autumn/Fall, and Winter. Each season brings different weather, hours of light, and plant/animal behaviors. The seasons are brought about by the yearly orbit of the earth around the sun and the tilt of the earth's axis. Below are the astronomical dates for the calendar year 2017 for both the northern and southern hemispheres.
