Hello, Ebrahim, 

Following the provided information, I was unable to reproduce the issue you are facing with the latest version of the Telerik UI for WinForms suite. Could you please specify what Telerik version you are using? 

According to the provided code snippet, it seems that you are using a PersianCalendar. Please have in mind that there is a known issue in the .NET Framework considering the "fa-IR" culture. Please refer to the following forum post:
https://www.telerik.com/forums/persian-culture-bug-in-rad-datepicker 

I have attached my sample project. Please give it a try and see how it works on your end. Am I missing something? Could you please specify the exact steps how to reproduce the problem? Thank you in advance. 

I am looking forward to your reply.

hi

my telerik version is WinForms_2021_3_1109

I have no problem with the Persianization of the calendar and it works properly
But this error occurs when the calendar is on a non-leap year and it is also the twelfth month and the user changes the day to thirty with the keyboard. But this error does not occur with the arrow keys.
I am filming this incident
Thankful

The provided videos are greatly appreciated. Actually, it is related to converting a DateTime to PersianCalendar:

After investigating further, I can confirm that this case can be handled in RadDateTimePicker.
