Do you know of Patrick's Chronodex radial day planner? Well you should. It is an interesting way to schedule your responsibilities, especially if you are more of a visual person. He offers it as a free download on his site and it has caught on so quickly, that several people have also offered modified versions for download as well. For example, there is a Circa version and a GTD version (both paper and digital (iPad) formats).
I'm really enjoying this format for my datebook, although I would like to make a few modifications when I have a bit more time. One thing I would really like to do is to create the radial days for the weekend, as much of my shop activities happen then. I would also switch out the AM and PM locations in the 9 to 12 time range, as much of my appointments occur in the evenings than the mornings. Ah, but, no time to make such changes now. Luckily, the datebook still works pretty darn well as it is.
I love how thin it is, so I can just keep it in my bag with my journal without adding extra weight. Oh, and it was so easy to make. The one addition I have done is to add my to-do list to the cover of my datebook. That way I can see what tasks I have to get done without opening my planner. Its like a nagging inanimate object, but without being annoying.
So, if you are looking for a new way to keep your appointments in 2012, take a look at the many variations of Chronodex. There is even a Flickr group for it so you can see how different people are using and modifying the system.
