Donald.
Many ways to solve your problem and I add mine as I use in my program ZW2000 to
calculate flat sundials .
The procedures are published on the website of De Zonnewijzerkring.

Look for:
- Calculate and construct.
- Flat sundials, extensive version.

Hello:
I need to write a spreadsheet to find the sun position. I know there
are already many programs that do this. However, I need to write one
myself because:
1. I'll learn as I write
2. It will give the sun position in the format that I need
3. I can tweak the spreadsheet to give the same
If there is a need for someone on the list to generate a programme for
astronomical positions in higher accuracy, I have already coded in C++,
a complete windows library that computes Galactic (GLat/GLng),
Ecliptical (Elat/ELng), Equatorial (Rta/Dec) and Horizontal (Alt/Azi)
positions of the
Hello Darek,
Thanks for sharing this link on sundials in the French Alps. I agree this is
a great area to search for sundials. We have been there many times
collection photos and information.
My interest focused on G. F. Zarbula who painted over 100 sundials in the
area between 1830 and
If you're looking for software libraries, I've been happy using these:
AA+ is a C++ implementation for the algorithms as presented in the book
Astronomical Algorithms by Jean Meeus.
