Building Sundials

Create your own sundial with MATLAB.

If carefully built, a sundial is perfectly capable of keeping accurate time. The problem is that you need a different sundial for every combination of latitude, longitude, and day of the year. Fortunately MATLAB® can make this a manageable problem. By turning this procedure around, you can also use MATLAB to tell you which way is north.

The algorithms used here for MATLAB sundial creation were adapted from https://www.dezonnewijzerkring.nl/
