I am sorry this answer will get to you a day late, but I just recieved it 
this morning (8/18).

The answer to your question however depends on where you live.  Circling 
the Earth are imaginary lines.  These lines are called the LATITUDE.  At 
"0" latitude you are at the Equator.  Here you will get nearly 12 hour of 
sunlight and 12 hour of darkness all year long each day.  As you move 
towards the North or South Poles you also move UP in latitude.  The 
further away from the equator you go the greater the differance in the 
number of hours of light and dark.  When you get to 90 degrees of latitue 
you are the North or South Pole.  Here you will get 24 hours of light in 
the summer and 24 hours of dark in the winter each day.

Depending on where you are in terms of latitude, you will get something in 
between the cycle of the equator and the cycle at the poles.
