Why does a gnomon on a sundial have to be 45 degrees?
Queenofhearts191
It doesn't.
The gnomon is supposed to match the latitude of the location where the sundial is placed. If the latitude is 30 degrees and the gnomon is 45 the entire sundial will have to be tilted to keep correct time.
Another way to describe this is to say that the gnomon should be parallel to the Earth's axis.

How do you calibrate a sundial?
The gnomon of a sundial is cut to a certain size depending on the latitude of the sundial's location. If the gnomon is not of the correct size, it can be compensated for by raising or lowering the lower edge of the sundial until all times are accurate. Calibration is fairly simple. Using a precise time measurement, when it is noon, go outside and position the sundial so the shadow of the gnomon is on noon on the sundial. Check it again at 1 pm, and adjust as needed.

Why did Brady Alan Easterday invented the sundial?
He didn't. The sundial, or gnomon has been used since antiquity.
How do you install a standard sundial in the Southern hemisphere?
There is no such thing as a standard sundial. For every different latitude (degrees north or south) the gnomon (the triangular shadow making bit) has to be cut differently. If you live 30 degrees south, cut the gnomon to a 30 degree angle. Set up the sundial so the sharp end of the gnomon is pointing exactly North. The easiest way is to just twist the assembled sundial until it shows the right time. If you want to be as accurate as possible you need to take longitude and time of year into consideration as well, but as most sundials are simply ornaments, that detail is not given.
Where would you find a gnomon?
The gnomon is the physical component of a sundial that casts a shadow onto the graduated scale for the purpose of timekeeping.
