Pi day is an irrational holiday that was invented by Big US Date Format.
@mattblaze Month goes before day in ISO form too, just not legacy European forms. Just the year placement differs.
@dalias @mattblaze year month day probably works better for mechanised filing systems.
But for a human being day month year is intuitive.
@peterbrown @dalias @mattblaze "But for a human being, second-minute-hour is intuitive" :)

@phl @dalias @mattblaze good point. But if you’re describing an event the time goes first and then the day then the month then the year. When it all fails of course is when you introduce the seconds elapsed and it goes minutes & seconds

But on mm dd yy the *only* country to use it is the USA.
Like gallons.

@peterbrown @dalias @mattblaze mm-dd is also the order of things in Hungary, Korea, Japan, China. yyyy-mm-dd to be precise, but listing mm-dd in the orderly and not backwards way is not at all a fringe American thing :D

And again, strangely, nobody seems to demand that minutes come forward or ounces before pounds and stones, or what have you, but *somehow* dd-mm is "just the way humans think" (it isn't, it's all just cultural, and as such it can be both popular and wrong at the same time).

@phl @peterbrown @mattblaze yyyy-mm-dd is just ISO form, which is what everyone *should* be using 😁
@dalias @phl @mattblaze yes, well momentarily *should* mean for a brief moment not “in a moment for eternity”.
And let’s not even go near trunk and gas.

@dalias @phl @mattblaze and I think most western European languages follow the DD MM YYYY format.

When it comes to standardisation, it would be good.
Then passenger airliners wouldn’t get halfway across the Atlantic and run out of fuel because they thought they were refuelling in kilos not pounds.
