Night

Night or nighttime is the period of time between the sunset and the sunrise when the Sun is below the horizon. This occurs after dusk. The opposite of night is day (or "daytime" to distinguish it from "day" as used for a 24-hour period). The start and end points of time of a night vary based on factors such as season, latitude, longitude and timezone.

At any given time, one side of the planet Earth is bathed in light from the Sun (the daytime) and the other side of the Earth is in the shadow caused by the Earth blocking the light of the sun. This shadow is what we call the darkness of night. Natural illumination is still provided by a combination of moonlight, planetary light, starlight, diffuse zodiacal light, gegenschein, and airglow. In some circumstances, bioluminescence, aurorae and lightning can provide some illumination. The glow provided by artificial illumination is sometimes referred to as light pollution because it can interfere with observational astronomy and ecosystems.

Famous quotes containing the word night:

    Don’t you know there are 200 temperance women in this county who control 200 votes. Why does a woman work for temperance? Because she’s tired of liftin’ that besotted mate of hers off the floor every Saturday night and puttin’ him on the sofa so he won’t catch cold. Tonight we’re for temperance. Help yourself to them cloves and chew them, chew them hard. We’re goin’ to that festival tonight smelling like a hot mince pie.
    Laurence Stallings (1894–1968)

    Every incident connected with the breaking up of the rivers and ponds and the settling of the weather is particularly interesting to us who live in a climate of so great extremes. When the warmer days come, they who dwell near the river hear the ice crack at night with a startling whoop as loud as artillery, as if its icy fetters were rent from end to end, and within a few days see it rapidly going out. So the alligator comes out of the mud with quakings of the earth.
    Henry David Thoreau (1817–1862)

    Listen, Ange, I’ve been looking for a girl every Saturday night of my life. I’m 34 years old, I’m just tired that’s all.
    Paddy Chayefsky (1923–1981)
