Halfevening

Halfevening refers to the period of twilight that occurs after sunset and before full darkness. It is a transitional phase of natural light characterized by the sun being below the horizon but still illuminating the sky through atmospheric scattering. This phenomenon is often divided into several stages, including civil twilight, nautical twilight, and astronomical twilight, each defined by the geometric position of the sun below the horizon and the degree of illumination. Civil twilight is the brightest phase, allowing for outdoor activities without artificial lighting, while astronomical twilight is the darkest, with the sky approaching complete blackness.

During halfevening, colors in the sky can become particularly vivid due to the longer wavelengths of light being scattered more effectively. The sky may display hues of orange, pink, and red as the sun's rays pass through a greater portion of the atmosphere. Many cultures and traditions have recognized halfevening as a significant time of day, often associated with reflection, the end of daily activities, or the beginning of evening rituals. Its duration and appearance vary depending on geographical location, season, and atmospheric conditions, such as the presence of clouds or dust.
