I'm not sure why, but that website is beautifully broken for me - it asked for my birthday (e.g. 25th Feb 1986) using a day / month / year form - then converted to the m/dd/yy form (i.e. a string 22586), - found that string in Pi, - forgot my birthday and messed up displaying that somehow when converting back - saying that it found my birthday of 22 / 5 / 86
