daytime - choose a jigsaw puzzle to solve

On Earth, daytime is roughly the period of the day during which any given point in the world experiences natural illumination from especially direct sunlight. Daytime occurs when the Sun appears above the local horizon, that is, anywhere on the globe's hemisphere facing the Sun. During daytime, an observer sees indirect sunlight while in the shade, which includes cloud cover. Other planets and natural satellites that rotate relative to a luminous primary body, such as a local star, also experience daytime of some sort, but this article primarily discusses daytime on Earth.
