What is dusk?

Dusk is the darkest stage of evening twilight. Usually it means civil dusk: when the Sun's centre sinks 6° below the horizon and outdoor activities start to need artificial light. Later come nautical dusk (12°) and astronomical dusk (18°), after which the sky is fully dark.

Phase	Sun below horizon	What you see
Civil twilight	0° to 6°	Enough light to work outdoors; brightest planets appear
Nautical twilight	6° to 12°	Horizon still visible at sea; bright stars visible
Astronomical twilight	12° to 18°	Sky looks dark to most people; faint glow remains
Night	more than 18°	No sunlight scattered in the sky

Dusk, twilight and the law

Many rules use civil twilight: for example, US aviation rules define night as the time between the end of evening civil twilight and the beginning of morning civil twilight, and several places set vehicle headlight times relative to sunset. Times are calculated in your browser from the Sun's position (the same method as NOAA-style solar calculators). They assume a flat horizon at sea level, so mountains, buildings and altitude can shift what you actually see by a few minutes.

Frequently asked questions

How long after sunset is dusk?

Usually 25–40 minutes at mid-latitudes, about 20–25 minutes near the equator, and much longer at high latitudes in summer.

Is dusk the same as twilight?

Twilight is the whole period of fading light after sunset. Dusk is the moment at the end of a twilight stage — normally the end of civil twilight.
