OK, I don’t already have a physical sun dial, but think I would like one.
These instructions seem overly complicated to me. And maybe not so accurate.
I live in Colorado, about 38 plus a fraction degrees latitude.
In the winter the sun shines from the south. In the summer mornings and evenings, the sun shines on the north end of the house, shines from the north into north facing windows. Is that heretical? I have been observing this for many years. If I had a sundial, wouldn’t it be working during all daylight hours, unless it was shaded?
Couldn’t I put a pin of some kind in the earth, pointing north, or plumb & vertical.
Then observe the shadow and mark it about mid day every day? When the shadow cast is the smallest, wouldn’t that be noon, local solar time. And there I could make a permanent physical mark.
Now here’s something I find interesting, according to a random internet article, the Romans had “daylight savings time”. The sundial had permanent marks, dividing the day into a specific number of hours, probably 12. The article stated that in the summer, the hours passed more slowly than in the winter. But I don’t know about that either. From my home, I gaze on distant horizons both east and west. I can easily observe that the sun doesn’t rise or set in the same place every day. Probably the number of degrees change between solstice and solstice is related to my latitude. But how could the location of the shadow on the sundial remain constant at sunrise and sunset each day… so until further explanations are presented, for me that shoots the theory of Roman DST .
I will need to make myself a sundial, make observations and adjustments until I understand these variables and how they interact before I can answer my own questions.
I just have this funny picture in my head of modern individuals following instructions on their computers to construct a stone age tool. 🤣🤣🤣
I assume we moderns are as capable as primitives. Same planet and star in same relation to each other… We differ only in our motivations to measure and mark the passage of time.
And upon reflection, I realize I DO have a sundial here. Some former owners installed a basketball hoop and backboard on a pole out in the driveway. Very likely it’s plumb. I can check it with my level. All I need to do is begin marking until I can discover when the sun is “directly overhead“. Then, I will know how far off sun time our local clocks are. But I don’t think the local powers that be will make any adjustments based on my sundial, and I am about 5 miles west of town, so town would not be on the same time as me anyway.🤣
I’m am not a fan of daylight savings time. “Hate it with a passion hotter than the sun.” I am SO GLAD I don’t have to coerce my circadian rhythms into the clock changes.
Much empathy to those who do!
