One source for latitude information is a book I recently published on sundial design now in its second printing. It uses matrix analysis applied to many planar sundials. Many of the examples show graphically the effects of latitude on sundial design characteristics.

Damn. There nothing worse than being pedantic and then making a sign error.
Thanks, Fer.

On subjects such as sundialling, I love people who are pedantic, anal, or the like. They are often the ones who best answer the question. For those who are splitting seconds and pushing the edge to make ever more accurate and unique dials, replies as yours are greatly appreciated. As a person

No that's NOT true! What does "everywhere" mean? If "everywhere" includes
the the dial face of a north wall dial, then it's not true. If you mean the
"flat" saurfacew of the earth, t
Hi Mike:
The tricky part of my question is figuring out the total number of hours of
sunlight a particular sundial face receives in a year.

I guess a horizontal is best - it will record the time from sunrise to
sunset.
As for latitude, isn't it true that everywhere on earth gets an average of
12 hours of daylight over a year?

Here's something for you to think about.
If you ask the question: What is the best latitude(s) for a particular type
of sundial? How would you answer that question? How would you define "best
latitude".
One way of defining best latitude(s) would be those latitudes where the
sundial type function
12 matches
