Need to explain a bit, a docking station is just an interface between the computer and some hardware like a monitor, keyboard, mouse, etc... Using one has nothing to do with a calendar. Need some details here, what type of PC, exactly what calendar program, etc...

These are docking stations http://www.amazon.com/b?ie=UTF8&node=778660, maybe you meant something else.
