A typical calendar like you see above contains a label for the month/year, a row of day name labels (or first letters in this case) and 6 rows of 7 columns of day number labels.
The layout consists of 1 Panel (pnl1). In that panel you can place the labels.
The panel will be anchored to all sides of the screen.
In the designer window of the IDE you place the Panel view (pnl1) in the MainPage file and adjust for the anchors. Save the file and you are ready to go on.
