The sunrise and sunset times can be calculated using the geo-coordinates. These times are then used for the dawn/dusk calculations. To make sure that the dawn/dusk calculation is performed using the geo-coordinates, drag it to the first position in the item dawn/dusk.
The geo-coordinates can be entered using the decimal point format. To find out which geo-coordinates your house has, simply go to www.maps.google.at and search for your house. Right-mouse click on your location and select “what is here?” to display your geo-coordinates (the first value is north and the second east).
If you wish to change the calculated times then activate the option “adjust time for dawn/dusk”. This will let you adjust how many minutes earlier or later you wish dawn and dusk to be.
