Dusk is the end of evening twilight

Dusk is the beginning of darkness in the evening, and occurs after twilight, (during which the sky generally remains somewhat bright and blue). Civil dusk is when the earth has rotated enough that the center of the sun is at 6° below the local horizon. This marks the end of the evening civil twilight, the point where artificial illumination is required to read outside. It can be confused with sunset, which is the point at which the earth has rotated enough that the sun is no longer visible from the local horizon.
