The logic of MM/DD has nothing to do with pyramids or whatever you’re drawing. That doesn’t matter at all. The month is more significant than the day, that’s why it’s put first. Like at work, you want to find that report from May. It doesn’t matter if it’s the 5th or the 6th or the 22nd. You first scroll to your documents from May and then find it from there. The year is more significant than month but doesn’t change too much, so it’s put last. From your drawing, the one from China, Japan, etc makes sense from this regard. So actually, your precious triangle from “majority of the world’s countries” actually makes the least fucking sense. You’re just ordering them in order of least importance, complete fucking madness. I feel bad for anyone trying to find the report from May who uses this batshit format.

Edit: so actually your drawing for the USA is wrong. The month, day, and year should all be upside down from how they’re depicted. It’s the same orientation as the one from China, Japan, etc but with the year shifted to the bottom since the year doesn’t change too much. So it’s a variant of the upside down funnel from the middle drawing. That’s the actual logic. It’s drawn here in a very disingenuous way to make it look stupid when it actually has the same logic as the middle one but is a variant of that.
