Hi Curtis,
You can edit the DayButtonStyle of RadCalendar. It uses triggers to change the visual appearance of the calendar cells. The triggers that determine the size of the day button can be adjusted to change their size.
Unfortunately the calendar buttons are presented in a uniform grid. After you modify the buttons you will have to somehow manage the panel's layout. You can use somewhat negative margins on the panel or use another panel.
Greetings,
