Hello Martina,
Setting aside the matter of Educational Authorities who cannot think (!), I
also agree that you might like to give this another go in order to allow the
Authority to think again.
There is another type of dial you might try on them – one that can also be
painted on the ground

Hi John,
I agree that in your circumstances it's eminently sensible to include the
longitude correction and then have only what is a universal correction to make
- that for EoT. That has to be more understandable and of course any dial
designed that way is then always within (about) a quarter

Hi,
Others have explained the problems regarding seeing/identifying/using
geostationary satellites to determine longitude but if you are prepared to
consider alternatives, there is one that simply uses radio and a clock.
Construct a device to work out local noon, like a north–south line.
Well, it's Dec then Inc for me - though I only have limited experience with
inclined dial design. Hmmm, I hadn't ever really rationalised it as you have.
An excellent topic.

I would be very interested to have a copy please. The incorporation of maps

Dear Linda,

Hi David,
You do provoke the most amazing interest! What sort of clients do you have for

Yes they are at the Globe Theatre. The dials are actually mounted on a
building at the edge of the New Globe Theatre Courtyard. You will recall that
there was great difficulty in finding the space to locate the Globe replica and
it is therefore quite close to other buildings.
The dials are

Fascinating. According to this web site (for schools!) you can do it and

Hi Keith,
They do not attract any more undesirables than any other public feature. The
warning is simply one to ensure that if any such does occur you cannot say you
were not warned!
It is true that any new feature attracts attention and interest and possibly
may even be regarded by some as a
Not really an answer to your question but if you accept the current half-year
instead of the current month, Chris Daniel's Dolphin Dial at Greenwich (SRN
2157 - The Queen's Silver Jubilee dial) has two plates by which each half of
the year may be accommodated but it is not adjustable by month..
I too like the description 'Moment Dial'. These don't just have to be limited
to one moment either and as John suggests they don't have to be in stained
glass. My favourite is the wonderful liberation monument in Guernsey, Channel
Islands (SRN 3230) designed by David Le Conte and Eric Snell.
