this control is still has some issues even in the version 4.1.40412.0
i had tried a lot of times to use a CalendarExtender to show a hijri calnedar in an Arabic website but nothing it was useless, firstly i changed the ToolkitScriptManager properties EnableScriptGlobalization and EnableScriptLocalization to True and added globalization to the web.config file as following
<globalization enableClientBasedCulture="false" requestEncoding="utf-8" responseEncoding="utf-8" fileEncoding="utf-8" culture="ar-SA" uiCulture="ar-SA"/>
now see the attached image to know the bugs
