(I'm not from the US) My brain pattern matched it as two numbers that have some relationship with each other, but It didn't even occur to me that it was a date until I visited the page. If it was written 16/11 I might have gotten it(the bigger number on the left makes it unlikely that it's a ratio of some sort which is how I read it intuitively). But what if it was 5/11 or 11/5, still no idea what it means without context. If it said "on 11/16" I would get that it's a date, but it would still take me slightly more energy to figure out which is the month as I don't associate the right number with the day, but the opposite. Keep in mind, if I look at it for more than 2 seconds I will figure it out, but if I need to spend more than a fraction of a second parsing a date, you have a UI problem.
