Horizontal Sundial Functions

 Cable Gnomon Support Structure


The gnomon's shadow shows Standard (watch) time if adjusted for The Equation of Time.


The shadow of the nodus shows the date and solar declination (on my heliochronometers only).

Brass Finial:

The finial's shadow shows the solar azimuth and altitude. It also shows the time and direction of sunrises and sunsets.


This applies tension to the cable gnomon to keep it perfectly straight.
