A horizontal dial to my understanding,has the hour plate, flat on the

It's not too difficult to draw the hour lines for a horizontal sundial for
the equator with the help of some friends from this list who provided very
useful programs and equations.
Some pictures of paper/card sundials that w
Whilst trying to search for the said program, I came across a BBC segment

There's a ring sundial sold by the same person. Does that work in Lat 1.03N?

Hi Despina,
A fabric sundial would be most "cool" and I think it is possible!
Maybe u could investigate "Horizontal Altitude dials".
The gnomon can be created by holding two edges up vertically and pulled taught
so that the side profile is an L shape. To use it, orient the gnomon to face

U guys are great!
Thx for the detailed explanations.
I now have a better idea of what's going on when I read those passages.

Hi,
Today as everyone knows is Good Friday. I was reading my bible and in the
following verse it mentions about the "sixth hour" and the "ninth hour".
Luke 23:44-45 It was now about the sixth hour, and darkness came over the
whole land until the ninth hour, [45] for the sun stopped shining. An

Most interesting read about WD40!
I should try some of the tips in there.

I would be weary of using WD40 on plastics. I sprayed some on the hinge of

Hi Gerard,
I'd like the dial to read in mean time because initially I'd like to be
able to skip the explanation of Local Apparent Time vs. Mean Time and
such.
It's not qite chronometer accuracy, but feel free to use modify the time
scale in this card ring dial.
It was done in MS Word.

I too don't get it.
Does anyone have a spreadsheet that computes a position from what was

Hi,
Thanks to the help I got here, I finally got the card universal ring dial
completed last night.

I haven't put it in the main index yet because I don't know if it is really
"universal". I only tested it in the month of May and June.

Hi Heiner,
I would recommend www.shadowspro.com
The free version is able to print several different types of sundials on
card that actually work! So it's almost free if your school already has a
computer and printer.
There's even a shadow animator to see how the shadow would look like at

That's interesting. I just printed out a polar Sundial from ShadowsPro and
it looked very similar to the horizontal sundial for my location.

Hi Frank, Richard and Thaddeus,
Thanks very much for your comments and URL pointers.
Looks like the differences in the different projections won't make much

Hi,
Another question I have, in books and write ups that I've read, often times,
there are references to longitude and latitudes to specify the dials/gnomon
sizes of sundials.
When I read about longitudes/latitudes in GPS articles, there are loads of
different types of projection used. A common
Hello,
I've always been fascinated by Sun dials and have just found this group
surfing around after making my first working Sundial using Shadowspro. It's
