Anyhow.

Let me see if I understand that correctly

    - Your code does not insert
* <2025-02-01>
    But instead
* Some heading 
:PROPERTIES:
:CREATED:  [2023-11-17 Fri 19:32]
:END:
   that is also ok, but for the moment I prefer the timestamp in the
   heading, because if I use outline-hide-body I obtain a nice overview
   with the dates.


    - Another problem is that I don't get your code to work for example
      the one in the file  auto-insert-created-timestamp-as-property.org
      gives me

Yes, I speak Spanish :)

To generate dates as you said, you can use the following code [0], on ~man date~ you can find other strftime format constructions, or alternatively, visit this [1]

The scheduled thing [2] had an if for certain conditions where you want that hook to get triggered (that uses specific buffer names that in my case are [2]), for a more simple approach, you might want to experiment with a simpler function [3]

I attach again the script migrate-from-ts-header-to-created-property.org because I got confused; I hope "soon" I could have a git public repo with my emacs config
