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.

* In Cochabamba, Bolivia (17 degrees latitude), the longest day has 13 hours, and the shortest day has 11 hours.
* In Germany (approximate latitude 50 degrees), the longest day has 16 hours, and the shortest day has 8 hours.
* Within the polar circles (any place that is within 23.5 degrees of the north pole or south pole), the longest day is 24 hours, and the shortest day is 0 hours.

Are the hours of daylight and darkness in September equal to March hours of daylight and darkness?
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)
What is the spring solstice?
The spring solstice is the beginning of Spring. (March 21st) There is no spring solstice only winter and summer. There are spring and fall equinoxes when the amount of daylight and darkness are the same (12 hrs each). A solstice occurs when darkness (winter) or daylight (summer) are at a maximum for the year. It is due to the tilt of the earth's axis of rotation relative to the plane it revolves around the sun in. Same thing that gives the seasons.
Does the South Pole daylight time last 24 hours?

How many hours of darkness are there in one day?
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.

About how many hours of daylight will there be in the Northern Hemisphere on the fall equinox?
