Key Differences
Sunset marks the exact moment when the sun disappears below the horizon, signaling the end of the daytime. This event is characterized by often vibrant colors in the sky, such as reds, oranges, and pinks. Twilight, on the other hand, is the period that follows sunset, during which the sky remains partially illuminated, despite the sun being below the horizon. This is due to the scattering of sunlight by the Earth's atmosphere.
There are different phases of twilight: civil, nautical, and astronomical, each defined by the sun's position below the horizon and the amount of light available. Sunset, however, is a singular event with no such phases.
Twilight provides a gradual transition from day to night, allowing for activities in the dimming light, whereas sunset often signifies the time to conclude daytime activities and enjoy the spectacle of the changing sky.
During sunset, the changes in the sky's color and light can happen rapidly, lasting only a few minutes in some geographical locations. Twilight, especially during the civil phase, can last much longer, providing a more extended period of diminishing light.
Culturally and artistically, sunsets often symbolize endings, closure, or the passage of time, while twilight can symbolize transition, ambiguity, or the threshold between day and night.

What exactly is the difference between sunset and twilight?
Sunset is the specific moment the sun goes below the horizon, while twilight is the period of dim light following sunset.
How do civil, nautical, and astronomical twilights differ?
They are distinguished by the sun's depth below the horizon, affecting the amount of natural light available.
Can twilight occur in the morning?
Yes, there's also a morning twilight before sunrise, often referred to as dawn.

What determines the colors seen at sunset?
The colors during sunset are influenced by atmospheric conditions, particles in the air, and the angle of the sun.
