Sunset or sundown is the daily disappearance of the sun below the horizon as a result of the Earth's rotation. The atmospheric conditions created by the setting of the sun, occurring before and after it disappears below the horizon, are also commonly referred to as "sunset". The time of sunset is defined in astronomy as the moment the trailing edge of the sun's disk disappears below the horizon in the west.
