the answer is Sweden it has 6 months of light and 6 months of darkness
that is the case because it is above the Arabic circle,witch is a circle around the northpole,extending down to a latitude of 23 degree's which is equal to the tilt of earth axis.
Because of the tilt of the axis, any place North of the Arctic circle will have sunlight 24 hours a day for half the year, and darkness the rest of the year, or at least twilight.
You can see how this works if you shine a light from across the room onto a globe which has the correct tilt of 23 degrees.
The Antarctic continent experiences days, weeks or months of no sunrises, depending on where you are on the continent.
During polar winters, the country that experiences no sunshine for six months is Antarctica. Areas within the Antarctic Circle are subject to continuous darkness for an extended period due to their extreme southern location.
Sweden is the country having six months day and six months night because it is located in the north pole. However I think that Antarctica is also having long days and long nights because it is in south pole.
The South Pole has about 6 months of continuous daylight from September to March, followed by about 6 months of continuous darkness from March to September. During the period of darkness, the South Pole has no direct sunlight for about 4 months.
The city with six months of continuous daylight followed by six months of continuous darkness is Longyearbyen in Svalbard, Norway. This phenomenon is due to its high latitude within the Arctic Circle.
Antarctica experiences six months of continuous daylight during the summer and six months of darkness during the winter due to its location near the South Pole.
Denmark
Depending on where you are on the continent, you can enjoy sunrises from about September to about March.
In certain parts of Alaska, some areas experience six months of continuous daylight during the summer and six months of continuous darkness during the winter due to their proximity to the Arctic Circle. This natural phenomenon is known as the Midnight Sun and Polar Night.
At the North Pole, a day lasts for six months, with continuous daylight for 24 hours during the summer months and continuous darkness for 24 hours during the winter months. This phenomenon is due to the tilt of the Earth's axis and its orbit around the sun.
During the winter months in the Arctic Circle, the night can last for up to 24 hours, meaning that there is continuous darkness for an entire day.
During the polar winter, countries located near the North or South Poles, such as Norway's Svalbard islands or parts of Antarctica, experience periods of continuous darkness where the sun does not rise above the horizon for several months.
