DayPilot is not supporting Arabic language

Hi team,
We are using daypilot in our web application. We are providing multilingual support to our client, Arabic language is one of those languages. We have tried this code snipped to change the orientation to RTL.

<div id="dp"></div>
<script type="text/javascript">
var dp = new DayPilot.Calendar("dp");
dp.rtl = true;
dp.init();
</script>

Please let us know if we are doing it a right way or not.

Thank you in advance.
