For many years I've used e.g. 2023 Mar 25, in the spirit of ISO 8601, to avoid all these problems. I say "in the spirit of" because, as I recall (it's been years since I read it), the standard is quite focused, whereas I just want to do Year/month/day regardless of other little details like punctuation / numeric vs named month / zero padded digits or whether there should be a timezone etc etc. Usually I'm just adding a date to private notes, so it really doesn't matter. When I have to fill out official forms on paper, I have to make an effort to change my habit.
