+    ### Extract information from the given date:
+    $month  = date("n", $this->date);
+    $year = date("Y", $this->date);
+    $day = date("d", $this->date);
+
+    ### Extract first day of the month:
+    $first = date("w", mktime(0, 0, 0, $month, 1, $year));
+        
+    ### Extract last day of the month:
+    $last = date("t", mktime(0, 0, 0, $month, 1, $year));
+
+    ### Calculate previous and next months dates:
+    $prev = mktime(0, 0, 0, $month - 1, $day, $year);
+    $next = mktime(0, 0, 0, $month + 1, $day, $year);

+    ### Generate calendar header:

+    $output .= "<TABLE WIDTH=\"100%\" BORDER=\"1\" CELLSPACING=\"0\" CELLPADDING=\"1\">\n";
+    $output .= " <TR><TD ALIGN=\"center\" COLSPAN=\"7\"><SMALL><A HREF=\"$PHP_SELF?date=$prev\">&lt;</A> &nbsp; ". date("F Y", $this->date) ." &nbsp; <A HREF=\"$PHP_SELF?date=$next\">&gt;</A></SMALL></TD></TR>\n";

+ 
+    ### Initialize temporary variables:
+    $nday = 1;
+    $sday = $first;
+   
+    ### Loop through all the days of the month:
+    while ($nday <= $last) {
+      ### Set up blank days for first week of the month:
+      if ($first) {
+        $output .= " <TR><TD COLSPAN=\"$first\">&nbsp</TD>\n";
+        $first = 0;
+      }
+        
+      ### Start every week on a new line:
+      if ($sday == 0) $output .=  " <TR>\n";
+    
+      ### Print one cell:
+      $date = mktime(24, 0, 0, $month, $nday, $year);
+      if ($nday == $day) $output .= "  <TD ALIGN=\"center\"><SMALL><B>$nday</B></SMALL></TD>\n";

+     
+      ### Start every week on a new line:
+      if ($sday == 6) $output .=  " </TR>\n";
+        
+      ### Update temporary variables:
+      $sday++;
+      $sday = $sday % 7;
+      $nday++;
+    }
+    
+    ### Complete the calendar:
+    if ($sday) {
+      $end = 7 - $sday;
+      $output .= "  <TD COLSPAN=\"$end\">&nbsp;</TD>\n </TR>\n";
+    }
+    $output .= "</TABLE>\n\n";
+
+    ### Return calendar:
