Heliodial: Sun Path & Position

Which way does the sun set from your garden, and when does the light go gold tonight? Heliodial works it out for any place and date and draws it on one dial. The dial is a sun-path diagram: the zenith in the middle, the horizon round the edge. Today's path runs across it in the colour of its light, cream at midday and gold in golden hour.
