In terms of the radiation intensity of the sun to the earth, the winter solstice is the smallest and the summer solstice is the largest. If the whole year is divided into four equal parts, the three months from the beginning of winter to the beginning of spring are the smallest, the three months from the beginning of spring to the beginning of summer are the middle, the three months from the beginning of summer to the beginning of autumn are the largest, and the three months from the beginning of autumn to the beginning of winter are the middle.
