I have two questions:

How many hours of light and darkness are there in June at regions south of the Antartic Circle (dotted line in Southern Hemisphere)?


Six months later, when the earth is at the December position, is the situation in the Antartic the same or is it the reverse?

Isn't that winter in the Southern Hemisphere, when the night is 24 hours?

Six months after winter, ....the sun does not set. Very hard to get to sleep.
