The character of the lighting is determined by the sun's altitude, and the time for the sun to move from the horizon to a specified altitude depends on a location's latitude and the time of year. [4] In Los Angeles, California , at an hour after sunrise or an hour before sunset , the sun has an altitude of about 10–12°. [ 5 ]
It is based on the reddish glow of the morning or evening sky, caused by trapped particles scattering the blue light from the sun in a stable air mass. [5] If the morning skies are of an orange-red glow, it signifies a high-pressure air mass with stable air trapping particles, like dust, which scatters the sun's blue light.
The lower the Sun is beneath the horizon, the dimmer the sky (other factors such as atmospheric conditions being equal). When the Sun reaches 18° below the horizon, the illumination emanating from the sky is nearly zero, and evening twilight becomes nighttime. When the Sun approaches re-emergence, reaching 18° below the horizon, nighttime ...
Summer days are longer than winter days, but the difference is no more than approximately two and a half hours. The daily path of the Sun is steep at the horizon the whole year round, resulting in a twilight of only about one hour and 20 minutes in the morning and in the evening. Solstice day arcs as viewed from 50° latitude.

In late afternoon, sunlight is particularly bright and glaring, because the sun is at a low angle in the sky. [8] The standard working time in most industrialized countries goes from the morning to the late afternoon or early evening — archetypally, 9: ...
