I am awake early this morning in Falls Church Virginia, near Washington DC and checked your solar calender for my time and location. Here is what I get, below. I copied the display numbers manually since most of them are changing, ignoring seconds. It took me a few minutes to copy them down so there is some spread between the first and last numbers due to the time I took to copy them and the calculations will be off by a few minutes.
My comments are in brackets to the right. I have a couple of English usage or typographical notes, but the main problem I see is that the values for Sunrise, Noon and Sunset time are static. All the other values (except those that are not supposed to be changing like the coordinates and the equation of time) change in real time on the screen. Sunrise, noon and sunset time do not change on the screen. The values are static and not correct for my time and location, as you can see. The JavaScript is a little too complicated for me to be able to follow without a lot of effort.
I am not clear about the meaning of "Noon Time". Maybe Local solar noon? In normal usage, "noon" would just mean 12:00.

Dear dialists, I have left in http://www.relojesdesol.org/UbiSolENG.html a beta version of what we intend to be (smth. like) the Dialist Companion of the 'Asociacion de Amigos de los Relojes de Sol' but that would probably become into 'yet another online solar calendar'... :-) We've implemented not so accurate algorithms because we would like the users could hack the JavaScript code and customize it to their needs, if they like to. However, the precision is enough for sundialing in dates around the year 2000.0 You are invited to test it and tell us if it doesn't work. I am afraid it has got some hidden flaws, but I am not completely sure if the flaws come from our code or from these strange dwarfs that lurk into navigators; so any comment will be welcome.
