March 20/21 and Sep 22/23 of each year
During the Autumn equinox the length of the day and night are nearly equal. The length of the day on the equinox is approximately twelve hours.
The equinoxes are the two dates each year when the day and the night are of equal length.
An equinox is the time when the day and night are of equal length in a day. It is also the time that the Sun is directly overhead at Earth's equator at noon. A solstice is the time when the day and night are the most different in length of time than any other time of the year. It is also the time that the Sun is farthest from being directly above the Earth's equator at noon.
Oh, dude, in the desert, the length of night and day is like everywhere else on Earth, about 12 hours each. It's not like the sun decides to take a siesta just because it's hot outside. So, yeah, you get your standard half-and-half deal in the desert too.
Because Earth rotates at a constant speed, so each day is the same length.

There is none. They are all the same length

No, the moonrise time changes each day due to the moon's orbit around the Earth. The moon rises about 50 minutes later each day, so it does not rise at the exact same time each day.
Serial weight measurements are taken at the same time each day. The exact time of day is irrevelant as long as the weight is measured consistantly, at the same time each day.
No frequency refers to how often you work out. Duration is how long each day.
36 hours
The full moon is not on the same day each month because a lunar month (the time between two full moons) is about 29.5 days long, which does not align perfectly with the calendar months which are either 30 or 31 days long (except February with 28 or 29 days). This misalignment causes the full moon to vary in date from month to month.
Because during the day the weather changes
Night and day are the same length of time. The sun is at declination zero.
