It depends on where you are and what season it is. If you are at the equator then there is 12 hours of daylight and 12 hours of night. If you are above the arctic circle then during the winter there is 24 hours of darkness each day, this will occur on Dec. 21st. If you are further above the arctic circle the darkness can last for months. During the summer there will be 24 hours of daylight on June 21st, and again this can last for months if you are very far north. The same is true for the South pole as well.

The northern hemisphere will have daylight due to the tilt of the Earth's axis. As the Earth revolves around the Sun, different parts of the hemisphere receive varying amounts of sunlight throughout the year. This results in longer daylight hours during summer and shorter daylight hours during winter in the northern hemisphere.
During the day it is light and during the night it is dark.
Daylight and darkness are equal during the vernal equinox.

For every one else, there are only two 24 hour periods during the year When daylight hours equal night hours. These two days are the Vernal and Autumnal Equinox. (Equinox means equal).
