Thanks

 If e.Day.Date.DayOfWeek.ToString = "Sunday" Then
            e.Day.IsSelectable = True
        Else
            e.Day.IsSelectable = False
        End If

Thanks anyways!

That wasn't what you asked:

How can I add only sundays in a calendar control?

If you asked:

How can I determine if the the day of the week is Sunday and enable it as
being selectable?

Then I might have been able to respond accordingly.

Thanks.
