Night or nighttime (sp. night-time or night time) is the period from sunset to sunrise in each twenty-four hours, when the Sun is below the horizon. The exact time when night begins and ends (equally true with evening) depends on the location and varies throughout the year. When night is considered as a period that which follows evening, it is usually considered to start around 9 pm and to last to about 5 am. Night ends with coming of morning at sunrise .
The word can be used in a different sense as the time between bedtime and morning. The word 'night' is used as a farewell ("good night") and sometimes shortened to "night." Unlike "good morning," "good afternoon," and "good evening," "good night" is not used as a greeting.Complete darkness or astronomical night is the period between astronomical dusk and astronomical dawn when the Sun is between 18 and 90 degrees below the horizon and does not illuminate the sky. As seen from latitudes between 48.5° and 66.5° north or south of the Equator, complete darkness does not occur around the summer solstice because although the Sun sets, it is never more than 18° below the horizon at lower culmination.
The opposite of night is day (or "daytime", to distinguish it from "day" referring to a 24-hour period). The start and end points of time for a night vary, based on factors such as season and latitude. Twilight is the period of night after sunset or before sunrise when the Sun still illuminates the sky when it is below the horizon. At any given time, one side of Earth is bathed in sunlight (the daytime) while the other side is in the shadow caused by Earth blocking the sunlight. The central part of the shadow is called the umbra.
Natural illumination at night is still provided by a combination of moonlight, planetary light, starlight, zodiacal light, gegenschein, and airglow. In some circumstances, aurorae, lightning, and bioluminescence can provide some illumination. The glow provided by artificial lighting is sometimes referred to as light pollution because it can interfere with observational astronomy and ecosystems.

"It was that glorious hour, with the daylight still glowing everywhere, but the moon already gleaming and the first bats dipping in the green, shimmering air. On the edge of the woods stood dissolving in the last light, bright chestnut trunks against black shadows. A yellow cottage softly radiated the daylight it had absorbed, glowing gently like a topaz. The small paths pink and violet, led through meadows, vineyards and woods..." - Hermann Hesse
