There isn't a country on Earth that is entirely devoid of sunlight. However, some regions within certain countries may experience prolonged periods of darkness due to specific geographic or climatic conditions. For example:
Polar Night: Near the Earth's poles, such as in parts of Norway, Sweden, Finland, and Russia, there are periods during winter when the sun remains below the horizon for extended periods. This phenomenon is known as the polar night. In some locations within the Arctic Circle, the sun does not rise above the horizon for several weeks or even months during winter, resulting in continuous darkness.
Extreme Latitudes: In regions located very close to the poles, such as parts of Antarctica, there can be variations in sunlight exposure throughout the year. During certain months, these regions may experience continuous daylight, while during other months, they may experience continuous darkness.
It's important to note that even during the polar night or in regions with prolonged darkness, there is still some level of twilight or residual daylight, although the sun itself may not be visible above the horizon.
However, when we consider countries as political entities, they encompass a wider range of latitudes, and there is always some level of sunlight, even if it varies throughout the year. So, while certain regions within countries may experience periods of darkness, no entire country is entirely without sunlight.
