But when we talk about day and night,we are using “ day ” to mean the time between sunrise and sunset. Since the earth looks like a ball,the sun can shine on only half of it at a time.

In South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more sunlight. Days are longer than nights.
