function getCurrentMonthLastDay(){
    var current=new Date();
    var currentMonth=current.getMonth();
    var nextMonth=++currentMonth;

    var nextMonthDayOne =new Date(current.getFullYear(),nextMonth,1);

    var minusDate=1000*60*60*24;

    return new Date(nextMonthDayOne.getTime()-minusDate);

  function getCurrentMonthLastDay(){
     var current=new Date();
     var currentMonth=current.getMonth();
     var nextMonth=++currentMonth;

     var nextMonthDayOne =new Date(current.getFullYear(),nextMonth,1);

     var minusDate=1000*60*60*24;

function getCurrentMonthFirstDay(){
    var current=new Date();
        current.setDate(1);
    return current;
