Year is defined as the period of revolution or orbit of one body around another body, particularly of Earth around the Sun. Earth performs this movement by following an elliptical path in space once every three-hundred sixty-five days. Earth's axis is also tilted 23.5 degrees to the plane of the ecliptic for the duration of this movement giving us the periodic cycle of the seasons.
