To all those who expressed interest in my sundial calendar project of a few
months ago, I have to inform you that I've decided not to go ahead with it.
It has turned out to be too difficult for me to gather enough material to
complete the project in the way I had envisaged.
Thanks to everyone

I think that an other problem of a large sundial, is the accuracy of the
shadow. Will the shadow be sufficiently sharp ?
Good luck and sunny skies !

I would like to know what problems may be anticipated in the
Well, all sundials (except rare focusing dials) cast a shadow whose blurred
edge is 2 minutes of time wide, corresponding to the 2 minute (of time) width
of the sun. This effect is just more noticable in large dials, but does not
enhace or lessen their accuracy.
