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.

God is keeping the night watch for you and for me
Bright stars are watching the world as it sleeps
Shepherds watch over the little white sheep
The lighthouse is shining for ships far at sea
As God keeps the night watch for you and for me
So sleep, sleep in peace and rest
Don't be afraid of the darkness
All's well for over the land and the sea
God's keeping the night watch for you and for me
God is keeping the night watch for you and for me
So sleep, sleep in peace and rest
Don't be afraid of the darkness
All's well for over the land and the sea
