In court cases I have worked on in the past, I needed to find the angle of the sun at a certain time of day to see if it was shining in a driver’s eyes or melting ice on an outdoor staircase. Here is a simple web site which will do the work for you. It might also be useful for garden planning or putting up solar panels. You can change the date and move the location around on a zoomable map. You can find the calculator at http://sun-direction.com/.
