4. Simpan Template

5. Selanjutnya letakkan kode berikut dimanapun anda ingin menampilkan Countdown Timer-nya. bisa di postingan, widget, dan static page. Tapi anda tidak bisa menampilkan 2 atau lebih countdown timer secara bersamaan.

<div id='countdown_def' class='timerArea' ></div>
<script>
$(document).ready(function() {
$("#countdown_def").countdown( {
dateEnd:'11/12/2014 18:05:30',
format:true,
callback:function(){alert('Def Ready')}
},
{
timezone:false,
offset:0
}
);
});
</script>

11/12/2014 18:05:30 adalah waktu akhir Countdown Timer.
Anda dapat menggantinya dengan tanggal dan tahun yang anda sukai.
Format tanggal mm/dd/yyy atau Bulan/Tanggal/Tahun.

Warning! pastikan dalam template anda sudah terdapat jQuery terupdate. Jika belum ada, silahkan anda menambahkan kode jQuery dibawah ini dan letakkan diatas </head>.

 <script src='http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.js' type='text/javascript'></script> 

Semoga bermanfaat..
