Fwd: solved: how to exclude several single dates from a diary block (was: how to exclude several single dates from a diary block)

[Rainer Thiel <r.thiel@uni-jena.de>]

Thank you very much, indeed, Ihor.  diary-date was exactly the
function I was looking for.

Please allow me to report that in the meantime I have found a method
that seems to suit my personal needs even better.  You can use

<%%(org-class 2022 04 11 2022 07 15 4 21 26)>

to set every Thursday (4) in the time range between April 11th, 2022
and July 15th, 2022, but exclude (the Thursdays in) ISO weeks 21 and
26 (ie, 2022-05-26 and 2022-06-30).  Less to type and easier to do if
your calendar carries ISO-week numbers.

Many thanks again for the help

Rainer
