You have two options:

1) put a reference to the DayPlanner instance in your MiniCalendar, then 
call a method on it in your event handler. That's the easiest way, 
though maybe better to use the main frame or App object as an intermediary.

2) Use a way to post an event indicating that the date has changed. You 
can either use custom wx event and wx.PostEvent to do that, or, even 
better, use a system like wx.lib.pubsub to pass events around your app. 
I think that's probably what you want.
