I found a problem with the date components for some reason the system will never accept that I enter a date of any first Sunday after the 15th of the month of October every year.

When I enter one of these dates and move the focus out of the component, the system automatically switches to the previous day.

You can notice the issue even in the pages of the demonstration site:
RadDatePicker
