It changes slightly every day, just like it does everywhere else on Earth.

On a single day, it could be anything between zero and 24 hours, depending

on the date, and exactly how far south of the Antarctic Circle you are. Over

the course of a whole year, it averages out to 12 hours for each day.

(Just like it does everywhere else on Earth.)

The Antarctic region south of 66 degrees S experiences at least one 24-hour period of no sunset/ sunrise each year.

At 90 degrees S, this period is six months.

Depending on where you are in the region, your summer daylight hours are generally more than the non-daylight hours.
