Is there a locale setting that uses the *sane* date format of "5/3/2026" and "5 March" instead of "3/5/2026" and "March 5"?

I thought en_IE did this but I just missed an appointment due to it being the wrong way around in GNOME calendar.

@allpurposemat What software are you using?
@yora I'm using "Calendar" from GNOME on my Linux phone. The shell interface (currently Phosh) also shows the date in american format, so I don't think it's a bug in a single app, but rather an issue in my locale choice.
