Hi Heiner:

That is incredible. > Do you have more info on the math of it? Here is the drawing of Roger Bailey's Seasonal Markers and how
they function. Roger is a Canadian member of NASS and is hosting the NASS
conference next year in Banff. He specializes in analemmatic
sundials. Contact him for a mathematical explanation of his Bailey Points.

Since some people don't know how the Bailey Points are used to
tell the times of sunrises & sunsets, here is a drawing that explains
them. If you stretch a string from a date on the dateline out beyond the
Time Ribbon so that it passes through the East Bailey Point (Seasonal Marker),
it will tell you the time of sunset on that date. In this drawing, as an
example, the purple line shows the time of sunset on Nov. 1. A similar
line through the West Bailey Point will give you the time of sunrise on that
date. Real simple!
