No country experiences three months of continuous darkness. The Earth's tilt causes seasons, and while some regions experience longer periods of darkness during winter, there's always some sunlight even at the poles.
The closest experience to three months of darkness is during the polar night at the Arctic and Antarctic circles.
- Arctic Circle: Located at approximately 66.5° north latitude, it experiences a period of continuous darkness lasting 24 hours during the winter solstice, which occurs in late December. This period gradually increases in duration as you move further north towards the North Pole.
- Antarctic Circle: Located at approximately 66.5° south latitude, it experiences a similar period of darkness during the winter solstice in late June.
While the sun doesn't rise above the horizon during this time, there's still a faint twilight period depending on the location and time of year.
It's important to note that the duration of darkness varies based on the specific location within the polar circles.
