JavaScript: Print previous 12 months -- "March" prints twice?

I'm trying to write a script that prints the names of the previous 12 months. Since this month is January, it should print: December November October September August July June May April March February January

Instead, it prints March twice. http://ift.tt/1tzEeF8

November October September August July June May April March March February

HTML

    <div id="test"></div>

Javascript

    monthNames = [ "January", "February", "March", "April", "May", "June","July", "August", "September", "October", "November", "December" ];
    d = new Date();

    for (i = 0; i < 12; i++) {  
        d.setMonth(d.getMonth() - 1);      
        monthName = monthNames[d.getMonth()];       
        $('#test').append(monthNames[d.getMonth()] + "<br>");       
    }

What am I doing wrong?
