There's no easy way to do either thing you're asking about. The stationery
file is just a collection of lines and boxes and static text containers.
You have to manually change the dates in each of the boxes. There's no way
to change the view either (short of making another blank template file
consisting of a monthly calendar's worth of empty boxes and up to 31 static
text containers. There is no database or dynamic data feeding that
template, and none that can be used in any OneNote file.
If you want to manage a calendar, I'd recommend using Outlook. Outlook is
intended to be Microsoft's calendar and scheduling program. If you want to
write or type on top of a calendar in OneNote, you can take a calendar in
Outlook and print it into OneNote either via the MODI print driver, or the
3rd party add-in found here:
