			For walls at some variance from being south facing, the hour lines would need to angled differently on each side of the dial. This is well explained on the British Sundial Society website - see [http://sundialsoc.org.uk/old/HDSW.php 'How do sundials work?' Part 18. '''Introduction to decliners''']

	Vertical Sundial		As with a '''Horizontal Sundial''' the '''[[Sundials and Gnomons\|Gnomon]]''' of a '''Vertical Sundial''' remains pointing North and set at an angle '''''to the horizontal''''' equal to the '''[[Latitude]]''' of the '''Sundial''' location. The '''[[Sundials and Gnomons\|Gnomon]]''' therefore must be set at an angle to the 'dial' of 90<small><sup>0</sup></small>. minus '''[[Latitude]]'''.
