diary sexp

[Raimund Kohl-Fuechsle]

Hiya,

I have a monthly meeting on the first Thu every month for the next 12
months.  Therefor I created a diary entry this way:

%%(diary-float '(11 12 1 2 3 4 5 6 7 8 9 10) 4 1) "The Easy Way
Discourses", Mannheim

Works.  No problem.

BUT:  I would like to have Emacs telling me the Discourse number ...
something like

"The Easy Way Discourses", No 3, Mannheim

Number 1 started in Nov, no. 2 will take place in Dec and so on.  How
can I do this?

cheers, ray
