Division of the year is a term used to refer to the four distinct periods of the year, which are spring, summer, autumn, and winter. These seasons are determined by the Earth's orbit around the sun and the tilt of its axis. Each SEASON has its own unique characteristics, such as temperature, precipitation, and daylight hours. The division of the year into these four distinct seasons is an important part of many cultures and is celebrated in various ways. The answer to the crossword puzzle is 'SEASON, ' which is a six-letter word that accurately describes the division of the year.
