This is because it depends on what latitude you are referencing. The amount of 'daytime' at the equator of a body is very different than the amount of 'daytime' at the pole, especially if the body's axial inclination is much greater than zero, and almost all known bodies in the solar system have inclinations substantially different than zero. > > A much more realistic question would be "what is the rotational period of Saturn?", and I have already supplied a link that explains that in some detail. I didn't change the definition: It reads number 1: the time between sunrise and sunset Day | Definition of Day by Merriam-Webster https://www.merriam-webster.com/dictionary/day 1 : the time between sunrise and sunset : daylight. https://www.google.com/search?q=define++++day&cad=h I had no idea 'your people' haven't yet figured out what a ..."Day" is yet. I guess asking, How Long Does a Day Last on Saturn? is too tough a question to ask...scientist. Is Day a theory?
