Today and always day is equal to night at the equator. But if today is the day of the vernal or autumnal equinox, then the day is equal to night in all other places of the Earth (except for the poles, of course).

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.
