Hello All,
I have been working on a vertical sundial and I have a question.
This South facingvertical has two time scales on it, one at the top
that shows thehour numbers to use during the period of the year when
Standard time is in effect, and one at the bottom to show the hour numbers to
Regarding the attempt to learn why the latest sunrise and sunsets don't fall
on the solstices, I think analemma.com has a pretty good explanation. I
suppose some background info and lingo is necessary to understand any
subject, and that site does a good job of giving the background for the
I believe that the simplified explanation of these concepts is very
important. Complex scientific overloading, however accurate, can
easily intimidate the casual user of one of our creations, to the
point of actually making them give up or lose interest in
understanding the concept at
Hi Jim,
Although it would be technically incorect to use the terms Standard Time and
Daylight Saving Time for these scales, I for one would not object as it does
convey the meanings to th general public. And it does serve as a
conversation-starter for us pedantic diallists ;-).
If you
Hello Jim,
To differentiate between the two scales perhaps you could use
roman numerals for one and arabic for the other. Also, may I suggest that
instead of putting them one above the other that you put one "inside" the other
so that they appear to be side by side. Perhaps you could

You can do whatever you like - you are the designer! If nothing else you

A sundial has to indicate local time, the solar time or natural time.
People that like to know the official time has to look on a watch.
That is all you have to explain to 'regular people'. They will understand
it.

To avoid confusing my clients, I just tell them that these irregularities
are due to the earth's tilt and elipital orbit and leave it at that. And
this satisfies them. (As soon as I mention the word orbit they know it's a
complcated subject and never press me for more information).

Hello All
Many of us communcate with each other using the wonderful PDF format for all
our documents. My clients love it because it is easily opened with Adobe
Acrobat Reader. But many people complain that they don't know how to make
them.
