Afternoon or evening is a time of the day after the day [1]. In the afternoon it becomes the liaison between day and night so that workers, students, employees and most people finish their activities in the evening to meet the night spent on rest.
In a tropical geographical region, the afternoon is between 15:00 and 18:00 when the sun begins to incline its light, the afternoon period in the region experiencing the four seasons may become longer or faster depending on the circumstances around. Some say the same afternoon ashar time, ie from the completion of the zuhur (the length of the shadow of the object exceeds the length of the object itself) to maghrib (beginning when the sun sets). The sun set here means that the entire "disk" of the Sun has "entered" under the horizon (horizon).
