A definition on the calendar:
Twi: civil Twilight, Dawn & Dusk
Civil twilight is defined as the time when the sun is 6 degrees below the horizon and up to the time it has risen, or the time between when it has set to when it is 6 degrees below the horizon. In the morning this time period is known as dawn—in the evening it is called dusk.
The end of dusk and the start of dawn are the limits at which illumination is sufficient, under good weather conditions, for terrestrial objects to be clearly distinguished; at these times, the horizon is clearly defined and the brightest stars are visible under good atmospheric conditions in the absence of moonlight or other illumination. In the morning before the beginning of civil twilight and in the evening after the end of civil twilight, artificial illumination is normally required to carry on ordinary outdoor activities.
The time displayed on this site is when the sun is 6 degrees below the horizon.
