Technically, one. The other days may suspect to be full of daylight but truly, they are shorter.
Antarctica receives zero hours of daylight in the winter.
24
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.
yes
Antarctica. Polar night (a period of time when the sun is completely behind the horizon) can last from 179 to 186 days.
During some summer days, daylight is visible for 24 hours: the sun doesn't set during those days.
In summer generally, there are 24 hours of daylight; in winter there are generally zero hours of daylight.
There are 1407.5 hours of daylight on Mercury which is 56.646 earth days!!
On December 25, all of Antarctica experiences 24 hours of sunlight.
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.
Antarctica experiences longer days in the summer due to its position near the South Pole. During the summer months, Antarctica is tilted towards the sun, causing the sun to stay above the horizon for longer periods of time. This phenomenon, known as the midnight sun, results in continuous daylight for several months.
No. Weather does not affect the sun.
