I wrote the following which allows me ctrl-c-ctrl-c on a date in an org file and thereby toggle the inactive state of the date. I find it useful when applying to courses that I am later [not] admitted to. Perhaps it is useful to someone else. Perhaps also there are obvious improvements to the code. Lastly, perhaps there is a better place to submit such snippets. I appreciate feedback.

You should be able to just use =org-toggle-timestamp-type=
instead of your snippet. It performs the check and will toggle
back and forth between active and inactive timestamps.

(add-hook 'org-ctrl-c-ctrl-c-hook
'org-toggle-timestamp-type)
