Whats wrong with this code?
var startDate = ['08','02','2006'];
// Forum Age var sta = new Date(); sta.setDate(startDate[0]); sta.setMonth(startDate[1]-1); sta.setYear(startDate[2]); var cur = new Date(); var dif = cur - sta; var totalMonth = 0; var totalYear = 0; var totalDay = Math.floor(dif/(60 * 60 * 24 * 1000)) + 1; while(totalDay > 365) { totalDay -= 365; totalYear++; } while(totalDay > 30) { totalDay -= 30; totalMonth++; } var age = totalDay+' days'; if(totalMonth > 0) age += ', '+totalMonth+' months'; if(totalYear > 0) age += ', '+totalYear+' year'; age += '.';

The plus 1 on the totalday variable seems to throwing things off by one day. Fundamentally the month/year counts will be off due to the fact that (leap) years and every other month is not 30 days. Correcting this by taking into account such variations into months will be a hefty amount of javascript. More or less out of boredom I cleaned up the code taking out the while loops <script type="text/javascript"> <!-- var startDate = ['08','02','2005'];
// Forum Age var sta = new Date(startDate[2], startDate[1] - 1, startDate[0]); var dif = (new Date() - sta) / 86400000; // milliseconds in day var age, display = new Array(0, 0, 0);
// Find Years if(dif >= 365) { display[0] = Math.floor(dif / 365); dif -= (display[0] * 365); // take days off total }
// Find Months if(dif >= 30) { display[1] = Math.floor(dif / 30); dif -= (display[1] * 30); // take days off total }
// Find Days display[2] = Math.floor(dif);
document.writeln(display[2] + " days, " + display[1] + " months, " + display[0] + " years"); --> </script>
