For any given place on earth, the amount of daily sunshine is due to the tilt of the earth's rotational axis with respect to the plane of its orbit and the fact that the direction in space in which the earth's axis points is almost constant as the earth revolves around the sun (one complete cycle of the direction or the earth's axial tilt with respect to the "fixed" stars takes about 25772 years).
The closer you get to the poles, the more variation there is in the amount of sunlight per day, and the closer you get to the equator, the less variation there is.
Saturday and Sunday
The seasons are already figured out . . . the seasons change on the equinoxes (days and nights of equal length) and on the soltices (days and nights are the most different in length)
The main factor that helps a chimpanzee adapt/evolve is enviromental pressures. An example of an eviromental pressure that that can effect a chimp is colder nights, as the nights get colder over time a chimps fur will become thicker in order to stay warm.
To calculate the length of stay in hotels, subtract the check-in date from the check-out date. For example, if a guest checks in on January 1 and checks out on January 5, the length of stay is four nights. Alternatively, you can count the number of nights booked directly, as the length of stay typically corresponds to the number of nights a guest occupies a room.

No they are not
divide the total number of booked nights by the total number of departures. IE. 635 room nights booked, with 195 departures length of stay is 3.3 days.
At the Equator at the two Equinoxes, Spring and Fall.
They are around the same length as days on Earth.
Nothing can change the length of day and night except the normal seasonal progression.
The seasonal variations in temperature and day length are greatest at higher latitudes, particularly near the poles. Areas within the Arctic and Antarctic Circles experience extreme changes, with polar days in summer when the sun doesn't set and polar nights in winter when the sun doesn't rise. Additionally, regions like Scandinavia and northern Canada experience significant temperature fluctuations throughout the year due to their distance from the equator.
Days get shorter and nights get longer until the winter solstice, at which point the days become longer and the nights become shorter.
