Only entering the month+year isn't the issue. The website is near random. I entered my DOB perfectly and was suggested i was an age decades off (with corresponding % being that wrong). Clearing cookies, meticulously entering and checking DOB again and i get decades off the other side of my age. The website is seriously malfunctioning. I guess it's just giving results of a different user.
