At the poles, there would be a day for six months, during which the sun would spiral up from the horizon to the zenith, then after a sunset that lasted for several days, a six-month night would come. At the equator, there would be seasons of long twilight twice a year, and for two seasons the sun would move across the sky roughly as it does now. At mid-latitudes, the length of the day would increase rapidly in spring, and then a day would last for many days, during which the sun would move in circles across the sky. In winter, a long night would come.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
