1 solar day is equal to how many hours
Day In common usage, it is either an interval equal to 24 hours[4] or daytime, the consecutive period of time during which the Sun is above the horizon. The word day may also refer to a day of the week or to a calendar date, as in answer to the question, "On which day?" The life patterns (circadian rhythms) of humans and many other species are related to Earth's solar day and the day-night cycle.
