There are periods of constant darkness anywhere inside the Arctic circle. This includes some of Alaska (see the map in the source list).
This is because the earth is tilted at 23.5 degrees or so, and some of the year, some or all of the top bit is tilted out of sunlight.
The second image linked in my source list will help you picture this. It shows the world in mid-summer (northern hemisphere), when the Arctic circle is always in sunlight, regardless of how much the earth rotates on its axis. When we're the other side of the sun from this, the opposite happens.

During winter in the Northern Hemisphere,the duraion of night time varies from half day to six months.This variation starts from a particular latitude and continues towards the poles.If Alaska happens to be in the particular latitude where the night time lasts for one month,then it is possible.

YES. ALASKA IS SO FAR NORTH THAT EVERY YEAR THE SUN IS NOT SEEN FOR WEEKS. ALSO IN THE SUMMER THERE ARE ABOUT 6 WEEKS IN WHICH THE SUN NEVER SETS. THIS IS CALLED THE MIDNIGHT SUN BECAUSE IF YOU WAKE UP IN THE MIDDLE OF THE NIGHT IT WILL STILLL BE LIGHT.

NO. Alaska is a huge state and it all depends where you are talking about. The further north you go the more extreme the daylight/no daylight hours go.
