Yeah I thought that was really confusing! I would have expected that for countries that commonly read left to right and count from small to big the format of day(smallest common date unit)/month/year(largest common date unit) would at least be a sensible default if unable to detect the exact clients country standard, failing that the ISO of YEAR-MONTH-DAY would be fine but not jumbling it up like this and putting the day between the month and year - I know my comment could sound a bit ‘flamey’ but I’m purely interested / invested from the point of view of logical or biology, I don’t care about ‘X country does Y better’.
