Our friend, Dr. Drang, gives a high-level look at these two stellar calendar applications for the Mac. I use Fantastical *and* BusyCal on my Mac. The former is [my primary calendar app](https://shawnblanc.net/2011/05/fantastical/) (since I work for myself from home now my life is not nearly as rigidly full of meetings and appointments as it once used to be). And for the times when I need a different view of my week or month I bust out [BusyCal](http://www.busymac.com/).

So long as we’re on the subject: I use [Agenda](http://getappsavvy.com/agenda/) on my iPhone, and Apple’s native Calendar app on my iPad.
