Context is everything.
“When are you guys coming over?”
“We were thinking 20th, but I couldn’t get off work then, so 21st it is.”
If you’re in that conversation, you’d be perfectly clear of what’s up. Imagine having to append “of December” to both dates (or also the year for that matter).
If it’s something more than a year ahead, then sure, I’ll include the month and the year - but that’s still going from most specific to least specific (i.e. day, month, year).









Might be an allergy. I used to have something like this with some foods some years ago. What’s interesting is that now I don’t seem to have it any more with the same foods; it might be true what they say about allergies - that they come and go. Not a medical professional - just speaking from my experience.
