How do areas of sunshine follow a patterns in a yard that has trees?

In a yard with trees, areas of sunshine are influenced by the position and height of the trees, as well as the sun's path throughout the day and seasons. During the day, sunlight creates shifting patterns of light and shadow, with areas closest to the trees receiving less direct sunlight, especially on the north side (in the Northern Hemisphere). Additionally, as seasons change, the angle of the sun alters, affecting the duration and intensity of sunlight in different parts of the yard. This results in a dynamic interplay of sunny and shaded areas that varies over time.
