I do write Lisbon, Portugal, whenever I talk about where I live. Doesn't take much extra effort to provide more precision and avoids possible confusions.
In a moment of whimsy I briefly considered a date format where digits were sorted alphabetically.
2026-07-02-16-31-52 -> -----00011222235667
Hopefully it will remain a nonsense and never be seen in the wild, unlike the phone number field which I found on a real website which responded to scroll events to increase and decrease the value it contained.
Well that's just totally ambiguous. What you should do instead is treat the date as one long number and present its factors, for instance 2⁴⋅11⋅7649⋅15050023, much more practical.
The European Commission published its own language guide. In terms of English it's only a small deviation from en-GB, but my first thought was indeed: when can I set en-EU?

as an American this is my favorite format. Sortable, and the mm-dd order reflects the standard American way of writing month+day, and yyyy is unambiguously the year since it's 4 letters. Best of both worlds.
I believe it's the ISO standard because it is obviously distinguishable from both the MM-DD-YY (US) date order and the DD-MM-YY (UK/EU/Others) date order and so is unambiguous.
Although my (AU) locale is dd-mm-yyyy, I'll use yyyy-mm-dd anywhere I have to write a date in all numbers to avoid any ambiguity. It also has the advantage of sorting correctly in things like file names.
For something more likely to be read by a human and not parsed by a computer (and is not locale or i18n/l10n flexible) I'll use d mmm yyyy, e.g., 3 Jul 2026. To my thinking, for English speaking this is the friendliest unambiguous format (although I'm sure opinions will differ).
"Friday 3 July 2026" (yes, I elected to spell out the month) also has the advantage of not requiring commas for legibility ("Friday, July 3, 2026" being common in the US).
Vad himla pratar du om? ALLT använder dd/mm-yy. Jag har aldrig sett något på svenska som använder yyyy-mm-dd, det finns bara inte. Det finns i Sverige, men då är det också på engelska.
Anything else is as bad as using mm:hh...
