Depending on where you are on the continent, the months can be from March to September. At the South Pole, for example, there is no sunrise during any of the listed months.
Antarctica receives zero hours of daylight in the winter.
December has the shortest number of daylight hours in Houston.
The day that has the shortest hours of daylight is known as the winter solstice. In 2013, the day that will have the shortest hours will be on Saturday, December 21, 2013.
Commonly, the 'shortest day of the year' everywhere is the day when there is the least amount of direct sunlight. On Antarctica the 'shortest day of the year' may contain no sunlight, because the sun doesn't rise -- or set -- every day south of the Antarctic Circle.
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.
That depends on where you were. In 2011 it was the day with least amount of daylight hours in the northern hemisphere and the day with the most amount of daylight hours in the southern hemisphere.

No. It has equal amounts of daylight and darkness. A winter solstice has the least amount of daylight and can be regarded as the shortest day of the year. If your clocks go forward once a year, then that particular day has 23 hours, so that could also be said to be the shortest day of the year.
It depends on your latitude.
