This is not possible. There is no built-in way of customizing the way that individual days or dates are displayed on the MonthCalendar control.

You could owner-draw the control, but that's way too much work to justify. This will make you responsible for drawing the entire control yourself. Note that if you choose to go this route, the MonthCalendar control does not raise the Paint event because the base control sets the UserPaint bit to "False". You will have to subclass the control and override its OnPrint method instead.
