In org mode I use a german time format for timestamps
(setq org-time-stamp-custom-formats '("<%a. %d.%m.%Y>" . "<%a. %d.%m.%Y %H:%M>"))
<Fr. 25.06.2021>. Internally this is represented as
So, I can for example
06-25 to find the time stamp, but searching for
25.06. doesn't work.
Is there any way to configure emacs such that it works to use
isearch-forward for a substring of the german time stamp representation?
