But, according to that I assumed and continue to assume that the format YYYY-MM-DD is accepted worldwide. Isn't it ?
The point I was alluding to is that according to Wikipedia, ISO 8601 covers representations of the Gregorian (and potentially proleptic Gregorian) calendar. That leaves out people running other calendars, like the Hebrew calendar, or Islamic calendar, or one of the dozen or more other calendars supported by OS X. Chances are such users may still want/have to deal with ISO 8601 dates, but they will presumably prefer to do it in a way that doesn't involve changing the calendar used everywhere in the OS, which is what changing to the ISO 8601 calendar in System Preferences will do. It's a bit like, oh, expecting everyone to set their language to English ;-)
OK.
I saw that setting YYYY/MM/DD as the two first default formats changed nothing to the two late ones which remain: 5 janvier 2015 et lundi 5 janvier 2015 When I applied the Hebrew calendar, the default calendar displayed: 5775/04/14 5775/04/14 14 Tébeth 5775 AM -- I don't know what's the meaning of AM here. It's not Ante Meridium lundi 14 Tébeth 5775 AM -- I don't know what's the meaning of AM here. It's not Ante Meridium today : Ven. 6 Elloul (5775)
With Arabian astronomic they become 1436/03/14 1436/03/14 14 rabia al awal 1436 AH lundi 14 rabia al awal 1436 AH today : Ven. 7 dhou. q. (1436)
It seems that the ISO 8601 is not so bad. I guess that - at least for dates of events belonging to this century, last one and next one there would be no ambiguity. I doubt that a swiss citizen will think that a check dated 1436/03/14 was issued at 1436/03/14 of gregorian calendar (same doubt about 5775/04/14).
According to wikipedia https://en.wikipedia.org/wiki/Date_format_by_country, the YYYY/MM/DD format is valid in numerous countries and I discovered that some make a difference between YYYY/MM/DD used for their traditional calendar and YYYY-MM-DD used for gregorian one. I tried to download some PDF linked in notes for arabic countries but all attempts result to "Safari don't find the asked page"
