Re: 08:09:10 11/12/13
Good comment and a logical alternative to the confusion. If people use MS Office and wish to use this format, it must be changed in Control Panel. When the pattern is added, the dates in Excel, Word, etc. default to the new format, at least the short date. Open Office seems to be able to handle any format regardless of Control Panel settings. But would logic catch on?

The /MM/DD format sorts numerically; something that I gravitated to when a lad with database set-up and administration. This format also seems the most logical to me. In the grand scope of things, the millenium, century, year, month, day typically take precedence in that order.

All of these differing date formats are confusing, as you can never really be sure which one people are using. Here in Canada, it's even worse because some people put the month first like in the USA and others put the day first and yet others put the year first! Nobody can be sure if something like 10/11/12 means October 11th 2012, November 10th 2012 or November 12th 2010! At least now that we're in 2013, some of that confusion is gone for the next 87 years. I think that the best way which everyone in the world understands is to start a four digit year: /mm/dd, and all the confusion goes away with the simple addition of two characters. Plus the dates can be easily sorted numerically. It's pretty much the only date format I ever use unless I spell out the month.

Re: Is East/West always at exact 'right-angles', to North/South?
Reminds me of someone a year or so ago who developed a method of determining the east of Mecca for prayer purposes regardless of how far north or south the location of the person is. In this case, east varies quite a bit. Another slightly off topic question your students may want to consider: if the earth rotates west to east, one would think there is some friction between the earth and the air causing the air to turn at a slower rate. This suggests winds should be out of the east. However, prevailing winds are often out of the west. Does this make sense?

Dear List Members (and experts!), I am a new member to this Mailing List - a school-teacher who can see the several curriculum benefits, of using sundials in (mainly Primary) schools. One of my pupils recently asked me a question, which seemed simple - but after thinking about it, now I am not so sure it has an obvious answer! Basically, is geographic East/West always at exact 'right-angles' to the direction of North/South - or is this affected by Latitude of location? On magnetic compasses, plus most maps (depending on the projection used), East/West is certainly at 90 degrees to North/South - but at (say) the North and South Poles there is no East or West direction at all, or are those locations just 'special cases' (being the exception to the rule)? That is what made me wonder, if East/West might depend on the Latitude. To keep things simple, I am only thinking about horizontal surfaces. I shall look forward to your replies, explaining whether East/West is always at 'right-angles' to North/South (or not, as the case may be).

Mini Universal Equatorial Sundial
(Subject changed to protect the innocent ;-) Hi Tony, Yes, it would be fun to finish one. I've got a Cowells, an old Atlas and a CNC Taig here and could probably complete it. The dials are quite nice. I hesitated to contact you figuring these were part or all of your livelihood. My current project is finishing a small skeleton clock to Colin Thorne's design and then I'm more or less free. But then there's John Wilding's Large Wheel clock to finish too. What drew me to sundials was the wife's desire to have a design on our south-facing garage wall and a declining vertical dial idea came up. The machining of it on relatively small equipment proved to be a bit difficult but it's still under consideration. This is a great list and I'm impressed by the many people contributing their time and effort to help others. Contact me off-list for details and thank you very much!

Interesting sundial
In a previous post (24 Jan. 2013), I thought a sundial in a photo was neat and wondered if there were plans for it. As a relative newcomer, I don't even know what kind it is. That post was apparently completely misinterpreted by an irritable being as something having to do more with those things that run on steel rails and not sundials. I merely responded to the subject line. My post and the response caused further OTs, for which I apologize. In any case, it is a neat sundial and I'd like to know more about it if the designer is not too P.O.d to respond.

I searched my inbox archive and see that you have only written one letter previously to the Sundial List back in 2011. In that letter you talk about FED EX and not sundials. See copy of your letter below. Let me respectfully clue you in on a few things… I have been on this mailing list for about 15 years I think, and as far as I know, there is no rule that we must only respond to the “subject at hand”. If this were the case, then no new subjects would ever appear. Often, several sundial-related subjects are discussed on the same day. However, since it is the Sundial List, most of us do try to limit our subjects to sundial related matter. My last letter was obviously about a sundial (a famous one by Tony Moss at that), and it included the best existing photos of that sundial as well as a photo of one of America’s only stained glass sundials. It was NOT about a “train set”. I don’t think I broke any Sundial List rules, and lots of people wrote to tell me they liked seeing the sundial photographs. The courteous thing for you to do would be to simply ignore letters that don’t interest you. We all do that. But none of us EVER tells anyone on the list to shut up. How rude was that! Think before you type. Sincerely, “that guy” p.s. You might want to do a grammar and spelling check on your letters before you send them. I’d be embarrassed if I were you. They make you look ignorant and uneducated.

Re: Construction of a vertical declining sundial
Thanks for the reply and to all who have provided suggestions. I was originally thinking of stainless steel for a skeletonized sundial but aluminum would be a lot easier to work. The basic frame would be round with the hour lines attached to it. There are a lot of outdoor items with power coated finishes and this was another consideration. The problem is how to bend a straight piece of SS or aluminum around a form to get a decent circular shape. The reflective properties of SS I had not considered. We have a home owners association here and I may have to get their approval of the design and a skeletonized metal sundial would seem to fit the bill. A painted dial would certainly be less trouble.

Stainless is not a good option for a number of reasons: expensive, hard to work and too reflective. I have used lightweight foam core sign board which is meant for outdoor use and paints well. With this material you could do something in the style of the vertical painted dials common in the Alps. Foam core sign board would probably not survive for a very long time, but your garage will probably not survive indefinitely, either. I made a dial for the side of my house by screwing plastic 3/4” square strips for hour-lines directly to the wall. It is a minimalist dial: line ends correspond to the solstices and there is a red mark for the equinoxes. The materials were easy to obtain (all from Home Depot) and work with.
