Could also be YYMMDD
In most of Europe it would be DDMMYY - but seeing how the English still measure stuff in feet and inches I wouldn’t be surprised if they have some illogical way of structuring the dates as well
I guess the confusing part is mostly because of an international audience. If everyone used MDY it would feel less weird. Still sorts completely wrong.
Where do you get that from? Is this a confusion with dates spoken or written out in full as "March the 9th, 2023"? We're talking numeric form here, "090323" in the specific example, and I don't think the UK has ever used MDY for numeric forms.
