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:
“The night has cut
each from each
and curled the petals
back from the stalk.”
—Hilda Doolittle (1886–1961)
“The moon shines bright. In such a night as this,
When the sweet wind did gently kiss the trees,
And they did make no noise, in such a night
Troilus methinks mounted the Troyan walls,
And sighed his soul toward the Grecian tents,
Where Cressid lay that night.”
—William Shakespeare (1564–1616)
“In every landscape, the point of astonishment is the meeting of the sky and the earth, and that is seen from the first hillock as well as from the top of the Alleghanies. The stars at night stoop down over the brownest, homeliest common, with all the spiritual magnificence which they shed on the Campagna, or on the marble deserts of Egypt.”
—Ralph Waldo Emerson (1803–1882)
