Sorry I can’t deliver straight or even right answer. But I can tell what I did on my forum.
American way to show dates is more confusing than ounces or other grain based metrics. I just can’t see intuitivitely differences between Feb 22 and Feb ’22. And showing a month before date number is just… let’s not say it at loud because here can be younger persons too 
Translations aren’t helping because even name of the moth changes, the structure of dates stays as american way quite often.
So fiirst I started hunt right terms (and 50 hits limit is really annoying when one doesn’t know exactly what is looking for). After that I googled right syntax, because pingvin-world just can’t use same syntax everywhere
Now I have this:
- all posts shows long date like
22. february 2023(no, we don’t use capitals with name of the months) - timeline shows shorter date, when a topic is more fresh, like
22. february - timeline shows 6 digit date when a topic is older, like
22.02.22(do you all see why dd.mm.yy is so logical, as ISO-metrics are )
I don’t know if that helped a bit. But we can edit terms — finding right one is the harder part of that job.
