I'm having a very difficult time deciding what you are asking, but perhaps
this is helpful. It sounds like you want to make sure each language has the
same files in it? For instance, given the existence of the files:
content/en/blog/file1.md
content/en/blog/file2.md
content/en/blog/file3.md
You want some sort of warning to be issued if only the following files
exist in another directory:
content/de/blog/file1.md
content/de/blog/file3.md
Is that correct? If so, you'll do something like

for file in content/en/blog/*.md; do
  basefile=$(basename "$file" .md)
  if [[ ! -e content/de/blog/"$basefile" ]]; then
    echo "German is missing $basefile";
  fi;
done;

Perhaps?

Maybe instead you're saying that the dates present in one language should
also be present in another language? That would be a pretty different
solution with which I'm happy to help if you indicate such a desire.
