During the summer months (December to February), Antarctica experiences continuous daylight known as the "midnight sun" or "polar day". The sun remains visible above the horizon for 24 hours a day due to the Earth's tilt towards the sun.
Conversely, during the winter months (June to August), Antarctica experiences continuous darkness known as the "polar night". The sun remains below the horizon for 24 hours a day due to the Earth's tilt away from the sun.
The exact dates when the sun rises and sets in Antarctica vary slightly from year to year due to factors such as the Earth's elliptical orbit and its precise position in relation to the sun. However, the general pattern of continuous daylight in summer and continuous darkness in winter remains consistent.
