Most of these cards get material of a planning/calendaring nature and my daily to do list material.

Do you have another calendar besides this card file?

A normal tickler file only has daily folders for the next 31 days, and information for specific days next month may not make it to the day specific folder until the month begins. For example, if today (November 24) I want to store something for December 27, I would put it in the December folder because the 27 folder is still being used for November 27. On November 27, I would move the folder to the December area, but I wouldn't go through the December folder looking for things filed for December 27; that would only happen on December 1. By the same token, information specific to December 3 may currently be in the December folder as opposed to the 3 folder.

All this is to say that a regular tickler file doesn't function well as a calendar. If I'm scheduling an appointment for next week, I want to be able to easily see what I have scheduled for a given day without having to sort through the December folder. So do you use something else for your main calendar?

I'm thinking about retiring my Filofax planner and looking for ideas for other analog options. Cards are pretty attractive for many of the different GTD subsystems, but I don't yet see their value for the primary calendar/planner.
