How long is the sunshine out for in Antarctica?

Answer 1

Antarctica is a continent as large as USA and Mexico combined, so there is no exact answer for the entire continent.

Everywhere south of the Antarctic Circle, the geogrphy experiences at least one 24-hour period of no sunrise -- and conversely, no sunset. So the number of 24-hour periods varies, depending on where you are on the continent.

At the South Pole, the most extreme location from the Antarctic Circle, the sun rises and sets once per year, so that the sun shines for six months and does not shine for six months.

Answer 2

Your answer depends on where you are on the continent and the time of year. Some days, the sun shines for 24 hours, other days, zero hours.
