Shows which parts of the world are in daylight, which are in twilight, and which are in darkness. The approximate positions of the sun and moon (projected on to the Earth) are also shown.
Various locations around the world can be selected, and the date and time can be changed. For the currently selected location and the current date and time, information such as the number of daylight hours and sunrise/sunset times are shown in the information panel.
The map can also be animated to show the passage of light and shadow across the surface of the Earth over time. The speed can be selected using the "Time Step" control.
The program makes some approximations; do not rely on the results to be totally accurate, they are intended as a guide only.
