I am so stupid, I looked at the manual for mktime and it just said hour,minute,second,month,day,year so I did not even bother to try it...but yes it works fine!! thanks so much...
if anyone else is reading this remember to add one because php arrays start at 0 🙂 cheers...
echo date('m/d/Y', mktime(0,0,0,1,105,2008));
