naplemente

Naplemente is the daily event at which the upper edge of the Sun disappears below the horizon, signaling the transition from day to evening in most inhabited regions. It occurs due to the rotation of the Earth relative to the Sun.

As the Sun sinks, sunlight travels through an increasing thickness of Earth's atmosphere. Shorter blue and violet wavelengths are scattered out of the line of sight by molecules and particles, while longer red and orange wavelengths dominate, producing the characteristic colors of sunset. The exact colors depend on the amount of aerosols, dust, humidity, and pollution, as well as the Sun's angle.

The moment of sunset is defined as when the upper limb of the Sun touches the horizon; twilight then continues until civil, nautical, or astronomical twilight ends. The duration of visible sunset and twilight varies with latitude and season; in high latitudes, twilight can last longer in summer, while near the equator it can be brief.

Cultural and practical aspects: Sunsets have long inspired art, literature, and photography, and are often associated with calm and transition. Photographers seek favorable conditions such as clear horizons and color-enhancing clouds; the golden hour occurs in the hour before sunset.
