For a little less than half the year, we had Sun at Scott Base, but that is over 1000km from the Pole. Very roughly, 3 months of all Sun, 3 months of all night, and the other bits some day, some night.
BTW, even in midwinter, it does not necessarily get completely dark, for there is still the Moon.
And one weird effect, was that going out on a sledge trip, and passing through the Moon shadow of some rock pinnacles, it felt as if it got colder! Rubbish of course, but that's how deep in our psyche good old Sol is.
So more directly to your question, it depends upon your latitude. If you type in your http bar "Daylight Hours" you should be directed to a great site ptaf.ca/soleil that presents you with graphs for any nominated place. I chose Mt Erebus, Antarctica.
Antarctica receives zero hours of daylight in the winter.
24
In Antarctica during October, which is springtime, daylight hours gradually increase as the continent transitions away from the long winter nights. By the end of October, locations like McMurdo Station can experience around 14 to 16 hours of daylight, with the sun remaining above the horizon for most of the day. However, specific daylight hours can vary depending on the exact location within Antarctica.
Sunny, clear, cold, windy and people are active. Some of these hours of daylight last 24 hours a day.
In summer generally, there are 24 hours of daylight; in winter there are generally zero hours of daylight.
same as summer and winter!
No. Weather does not affect the sun.
On December 25, all of Antarctica experiences 24 hours of sunlight.
Most everywhere on the continent, this number is 24 sunny hours out of 24 hours in a day.
18 hours
Depends on the location. North of the Arctic Circle, December clocks in with "zero" hours of daylight, while on Antarctica, June is the darkest month.
Scientific stations in Antarctica usually operate on the local time for the government that they serve. There is no standard time in Antarctica. If the country headquarters is on daylight savings time, then so is the Antarctic base. However, when the sun is up 24 hours out of the day, there's not much value to the notion.
