This project shows an example of a day-night cycle. The code you create controls various aspects such as the rotation of a light around the scene representing the sun, the transition between 2 or more skyboxs to simulate the sunrise / sunset / sunset and it also has a system to add events that occur when the transition from one state of the day to the other ends. In the video for example, lights can be seen lighting up when the day ends and the night starts.
