echo date("M-d-Y", mktime(0, 0, 0, 13, 1, 1997))."<br>";
echo date("M-d-Y", mktime(0, 0, 0, 1, 1, 1998))."<br>";
echo date("M-d-Y", mktime(0, 0, 0, 1, 1, 98))."<br>";

//Hasilnya semua sama : Jan-01-1998

<?php
$besok  = mktime(0, 0, 0, date("m")  , date("d")+1, date("Y"));
$bulankemaren = mktime(0, 0, 0, date("m")-1, date("d"),   date("Y"));
$tahundepan  = mktime(0, 0, 0, date("m"),   date("d"),   date("Y")+1);

echo "Besok : ".date("d M Y",$besok)."<br>";
echo "Bulan kemaren : ".date("M Y", $bulankemaren)."<br>";
echo "Tahun depan: ".date("Y", $tahundepan)."<br>";
