I'd like to clobber the fool who thought they'd be all unique and mess with the clean, traditional day/month/year system.
I cannot tell you how many times I've been misled with important/historic dates because of that stupid month/day/year rubbish. For example, the 12/01/18 can mean January or December, depending on the format. Sometimes there's *NO* way of knowing, so you're totally stuffed...
