Night or nighttime is the period of time when the sun is below the horizon. The opposite of night is day (or 'daytime' to distinguish it from 'day' as used for a 24-hour period). The start and end times of night vary based on factors such as season, latitude, longitude and timezone.
Nights are shorter than days on average due to two factors. One, the sun is not a point, but has an apparent size of about 32 minutes of arc. Two, the atmosphere refracts sunlight so that some of it reaches the ground when the sun is below the horizon by about 34 minutes of arc. The combination of these two factors means that light reaches the ground when the centre of the sun is below the horizon by about 50 minutes of arc. Without these effects, day and night would be the same length at the autumnal (autumn/fall) and vernal (spring) equinoxes, the moments when the sun passes over the equator.
