Why is there day time and night time on mars?
Mars has day and night for the same reasons that Earth has day and night. Mars, like Earth, rotates on an axis. That means that the Mars is spinning like a top. As the planet spins, half of it is facing the sun, and the other half isn't. So the half that is facing the sun experiences daytime, and the other half has nighttime. The planet spins around so the the same half is facing the sun every 24.6 (almost 25) hours. This is the same way that we see night and day, except Earth spins a little faster, so we have a complete day and night every 24 hours.

Does antarctica have 6 months of day and 6 months of night?
Not all of it -- only a tiny region near the South Pole experiences 6 months of continuous daylight followed by nearly 6 months of continuous night. The North Pole has a similar division between day and night, each lasting one half of the year. However, practically all of Antarctica experiences at least 24 hours of continuous day or night, and weeks or months of continuous day or night occur in various locations. *Because of the width of the solar disc, and refraction by the atmosphere, there are about 2 or 3 more days of daylight per year than there are of night.
