Do you know any DateTimePickers for calendars other than the Gregorian calendar?
Can you be more specific as to which type of Calendar you are interested in?
There is a Farsi calendar control available on code project: http://www.codeproject.com/KB/selection/FarsiLibrary.aspx
try the RadControls: RadCalendar for ASP.NET AJAX: http://www.telerik.com/products/aspnet-ajax/calendar.aspx RadCalendar for WinForms: http://www.telerik.com/products/winforms/calendar.aspx
