Hi Yogita,
Thank you for contacting Syncfusion support.
We have checked your reported issue “SfCalendar Navigation Button functionality in Arabic Language”. The Navigation button operation will be reversed when RTL is enabled in the SfCalendar. The left navigation button will work as a forward button, whereas the right navigation button will work as a backward button and it is an expected behavior of calendar. we have prepared a simple sample for the same, please find the sample link form below,
Please find the output for the same,
We hope that this helps you, kindly revert us if you have any concern.
