Day and night varies throughout the year depending on the angle of the sun and the axis of the earth. The further you are from the equator the greater the differences. If you live on the equator the difference is virtually nil.
They're the same length on either side of the date of the equinox, which falls in March and September. In 2009 those dates were 3/20 and 9/22, respectively. Just count days on either side of those dates, to answer our question. What ends up happening, is that the first 20 days of March will have roughly the same length of daylight as the 20 days AFTER the September equinox (i.e. 9/22 thru 10/11). Similarly, the first twenty days of September will have the quality of daylight shown for the first 20 days after the spring equinox (3/20 thru 4/9)
At the equinoxes, day and night are roughly equal in length at all latitudes. During the summer solstice in the Northern Hemisphere, there are long daylight hours and short darkness hours, while in the Southern Hemisphere it experiences the opposite. The winter solstice is reversed, with longer darkness hours in the Northern Hemisphere and longer daylight hours in the Southern Hemisphere.
Countries located along the same longitude lines will have the same daylight hours. For example, Spain and Algeria have daylight at the same time as they are both located in the same timezone (UTC+1).
Yes, for the six-month period between its sunrise about September 21 and its sunset about March 21 the daylight time lasts 24 hours at the South Pole. The same is true at the North Pole, and the events occur on the same days, in opposition.
You sleep the same. Just at different hours.
It depends on your location, in some places they are
The length of day in any desert depends upon its latitude and the season of the year. It has nothing at all to do with the fact that it is a desert. A desert would receive the same amount of daylight as a non desert region at the same latitude.

21 April and 21 September.
It depends on where you are and what season it is. If you are at the equator then there is 12 hours of daylight and 12 hours of night. If you are above the arctic circle then during the winter there is 24 hours of darkness each day, this will occur on Dec. 21st. If you are further above the arctic circle the darkness can last for months. During the summer there will be 24 hours of daylight on June 21st, and again this can last for months if you are very far north. The same is true for the South pole as well.
The day when the number of daylight hours is equal to the number of darkness hours is known as the equinox. This occurs twice a year, usually around March 20th and September 22nd. At these times, the Earth's axis is not tilted towards or away from the sun, resulting in almost equal day and night.
March equinox and September equinox : Daylight and darkness are of equal length on both the Vernal Point (Spring/March 20th 2011) and the Autumnal Point (Autumn/September 23rd 2011) .
At the equinoxes, day and night are roughly equal in length at all latitudes. During the summer solstice in the Northern Hemisphere, there are long daylight hours and short darkness hours, while in the Southern Hemisphere it experiences the opposite. The winter solstice is reversed, with longer darkness hours in the Northern Hemisphere and longer daylight hours in the Southern Hemisphere.
The lengths of days and nights in the desert are the same as with any area of the world at the same latitude. In the summer the nights are short while in the winter the nights are long. Over a year's period they average 12 hours of daylight and 12 hours of darkness per day.
An equinox is not the shortest day. It has the same amount of daylight and darkness. The solstices have the longest and shortest days. The winter solstice is the shortest day of the year in terms of the amount of daylight.
The equinox is the point in time where the Sun crosses the equator and there is no tilt to the Earth, thus there are approximately the same number of hours of light and darkness in both hemispheres. The term "equinox" comes from the Latin aequus (equal) and nox (night).
Countries located along the same longitude lines will have the same daylight hours. For example, Spain and Algeria have daylight at the same time as they are both located in the same timezone (UTC+1).
