Honestly DD/MM/YYYY makes more sense writing because it's "the 7th of June"
but MM/DD/YYYY makes more sense reading because you just read it as "June 7th"
dd/mm/yy is more accurate than mm/dd/yy because many people will get confused with mm/dd/yy and just say 6th july is the real 6/7 date.
thus dd/mm/yy is implemented in alot of countries so ofcourse, many people get confused and think its 6th july.
