Answer 1

I think your math is just a little off, and I tidied your syntax;

function getPreviousMonday()
{
    var date = new Date();
    var day = date.getDay();
    var prevMonday = new Date();
    if(date.getDay() == 0){
        prevMonday.setDate(date.getDate() - 7);
    }
    else{
        prevMonday.setDate(date.getDate() - (day-1));
    }

    return prevMonday;
}

That way you always get the last Monday that happened (which is 7 days ago if today is Monday)
