Galab

Galab is the part of the day that begins when the sun moves toward the west and ends when darkness arrives. It falls between afternoon and night. During this time, natural light decreases and temperature generally drops, especially in warm regions.

Evening has no precise scientific definition. It is a general term based on people's perception and social custom, not a measurable unit like hours. Its duration therefore varies by culture and location.

Light and sunset

During evening, the sun passes below the eastern horizon, causing sunset. After sunset, a small amount of light remains, known as twilight, because the upper atmosphere continues to reflect sunlight. The duration of twilight depends on latitude and season: it is short near the equator and much longer in high-latitude regions.

Social use

In many cultures, evening is when work stops, families gather, and the evening meal is prepared. The greeting "good evening" is a common way to address people at this time. Some media outlets and business schedules divide evening into specific periods, for example in evening entertainment programming.

Somali language and divisions of the day

In Somali, the day is divided into periods called subax, barqo, duhur, galab, fiid, and habeen. Evening typically begins in the afternoon and ends when the sun sets. The boundaries of these terms are not fixed and overlap in everyday use.
