2013-02-27 is also unambiguous.
Hey what’s today’s date?
It’s 2025 -
No like the DAY?
Yeah, it’s 2025, 02 -
Not the month, the day - What’s today’s actual date?
Like I was saying, if you’d let me finish, “2025 - 02 - 27”
I’m mostly joking, but when it comes to info about dates, I think the most evctive format it one that organizes the information within a heirachy that provides follow up answers.
Formatting dates as day / month / year does just that. Provides the day it is, followed by the month and year as that is the order that information is usually needed in.
I find providing the year first (or month) is much more ambiguous as neither are the day the actual date falls on.
Worse than that - they’re trying to tell us what we can spend our money on.
Which according to the horse shit Citizens United ruling is free speech for corporations. But not the people in em I guess.
