   <?php
   class Calendar {
   public function __construct(){
   $this->naviHref = htmlentities($_SERVER['PHP_SELF']);
   }
   /********************* PROPERTY ********************/
   private $dayLabels = array("Mon","Tue","Wed","Thu","Fri","Sat","Sun");
   private $currentYear=0;
   private $currentMonth=0;
   private $currentDay=0;
   private $currentDate=null;
   private $daysInMonth=0;
   private $naviHref= null;
   /********************* PUBLIC **********************/
   /**
   * print out the calendar
   */
   public function show() {
   $year = null;
   $month = null;
   if(null==$year&&isset($_GET['year'])){
   $year = $_GET['year'];
   }else if(null==$year){
   $year = date("Y",time());
   }
   if(null==$month&&isset($_GET['month'])){
   $month = $_GET['month'];
   }else if(null==$month){
   $month = date("m",time());
   }
   $this->currentYear=$year;
   $this->currentMonth=$month;
   $this->daysInMonth=$this->_daysInMonth($month,$year);
   $content='<div id="calendar">'.
   '<div class="box">'.
   $this->_createNavi().
   '</div>'.
   '<div class="box-content">'.
   '<ul class="label">'.$this->_createLabels().'</ul>';
   $content.='<div class="clear"></div>';
   $content.='<ul class="dates">';
   $weeksInMonth = $this->_weeksInMonth($month,$year);
   // Create weeks in a month
   for( $i=0; $i<$weeksInMonth; $i++ ){
   //Create days in a week
   for($j=1;$j<=7;$j++){
   $content.=$this->_showDay($i*7+$j);
   }
   }
   $content.='</ul>';
   $content.='<div class="clear"></div>';
   $content.='</div>';
   $content.='</div>';
   return $content;
   }
   /********************* PRIVATE **********************/
   /**
   * create the li element for ul
   */
   private function _showDay($cellNumber){
   if($this->currentDay==0){
   $firstDayOfTheWeek = date('N',strtotime($this->currentYear.'-'.$this->currentMonth.'-01'));
   if(intval($cellNumber) == intval($firstDayOfTheWeek)){
   $this->currentDay=1;
   }
   }
   if( ($this->currentDay!=0)&&($this->currentDay<=$this->daysInMonth) ){
   $this->currentDate = date('Y-m-d',strtotime($this->currentYear.'-'.$this->currentMonth.'-'.($this->currentDay)));
   $cellContent = $this->currentDay;
   $this->currentDay++;
   }else{
   $this->currentDate =null;
   $cellContent=null;
   }
   
   return '<li id="li-'.$this->currentDate.'" class="'.($cellNumber%7==1?' start ':($cellNumber%7==0?' end ':' ')).
   ($cellContent==null?'mask':'').'">'.$cellContent.'</li>';
   }
   /**
   * create navigation
   */
   private function _createNavi(){
   $nextMonth = $this->currentMonth==12?1:intval($this->currentMonth)+1;
   $nextYear = $this->currentMonth==12?intval($this->currentYear)+1:$this->currentYear;
   $preMonth = $this->currentMonth==1?12:intval($this->currentMonth)-1;
   $preYear = $this->currentMonth==1?intval($this->currentYear)-1:$this->currentYear;
   return
   '<div class="header">'.
   '<a class="prev" href="'.$this->naviHref.'?month='.sprintf('%02d',$preMonth).'&year='.$preYear.'">Prev</a>'.
   '<span class="title">'.date('Y M',strtotime($this->currentYear.'-'.$this->currentMonth.'-1')).'</span>'.
   '<a class="next" href="'.$this->naviHref.'?month='.sprintf("%02d", $nextMonth).'&year='.$nextYear.'">Next</a>'.
   '</div>';
   }
   /**
   * create calendar week labels
   */
   private function _createLabels(){
   $content='';
   foreach($this->dayLabels as $index=>$label){
   $content.='<li class="'.($label==6?'end title':'start title').' title">'.$label.'</li>';
   }
   return $content;
   }
   
   
   /**
   * calculate number of weeks in a particular month
   */
   private function _weeksInMonth($month=null,$year=null){
   if( null==($year) ) {
   $year = date("Y",time());
   }
   if(null==($month)) {
   $month = date("m",time());
   }
   // find number of days in this month
   $daysInMonths = $this->_daysInMonth($month,$year);
   $numOfweeks = ($daysInMonths%7==0?0:1) + intval($daysInMonths/7);
   $monthEndingDay= date('N',strtotime($year.'-'.$month.'-'.$daysInMonths));
   $monthStartDay = date('N',strtotime($year.'-'.$month.'-01'));
   if($monthEndingDay<$monthStartDay){
   $numOfweeks++;
   }
   return $numOfweeks;
   }
   /**
   * calculate number of days in a particular month
   */
   private function _daysInMonth($month=null,$year=null){
   if(null==($year))
   $year = date("Y",time());
   if(null==($month))
   $month = date("m",time());
   return date('t',strtotime($year.'-'.$month.'-01'));
   }
   }

2. Selanjutnya buat Script Css-nya(untuk tampilan), Silahkan copy scriptnya di bawah ini. lalu kasih nama calendar.css

   /*******************************Calendar Top Navigation*********************************/
   div#calendar{
   margin:0px auto;
   padding:0px;
   width: 602px;
   font-family:Helvetica, "Times New Roman", Times, serif;
   }
   div#calendar div.box{
   position:relative;
   top:0px;
   left:0px;
   width:100%;
   height:40px;
   background-color: green ;
   }
   div#calendar div.header{
   line-height:40px;
   vertical-align:middle;
   position:absolute;
   left:11px;
   top:0px;
   width:582px;
   height:40px;
   text-align:center;
   }
   div#calendar div.header a.prev,div#calendar div.header a.next{
   position:absolute;
   top:0px;
   height: 17px;
   display:block;
   cursor:pointer;
   text-decoration:none;
   color:#FFF;
   }
   div#calendar div.header span.title{
   color:#FFF;
   font-size:18px;
   }
   
   div#calendar div.header a.prev{
   left:0px;
   }
   div#calendar div.header a.next{
   right:0px;
   }
   
   
   
   /*******************************Calendar Content Cells*********************************/
   div#calendar div.box-content{
   border:1px solid #787878 ;
   border-top:none;
   }
   
   
   div#calendar ul.label{
   float:left;
   margin: 0px;
   padding: 0px;
   margin-top:5px;
   margin-left: 5px;
   }
   div#calendar ul.label li{
   margin:0px;
   padding:0px;
   margin-right:5px;
   float:left;
   list-style-type:none;
   width:80px;
   height:40px;
   line-height:40px;
   vertical-align:middle;
   text-align:center;
   color:Green;
   font-size: 15px;
   background-color: transparent;
   }
   
   div#calendar ul.dates{
   float:left;
   margin: 0px;
   padding: 0px;
   margin-left: 5px;
   margin-bottom: 5px;
   }
   /** overall width = width+padding-right**/
   div#calendar ul.dates li{
   margin:0px;
   padding:0px;
   margin-right:5px;
   margin-top: 5px;
   line-height:80px;
   vertical-align:middle;
   float:left;
   list-style-type:none;
   width:80px;
   height:80px;
   font-size:25px;
   background-color: lightgreen;
   color:#000;
   text-align:center;
   }
   :focus{
   outline:none;
   }
   div.clear{
   clear:both;
   }

3. Setelah itu Copy script di bawah ini, lalu beri nama index.php

   <html>
   <head>
   <link href="calendar.css" type="text/css" rel="stylesheet" />
   </head>
   <body>
   <?php
   include 'calendar.php';
   $calendar = new Calendar();
   echo $calendar->show();
   ?>
   </body>
   </html>
