I'm not sure why David Allen is so averse to using the calendar as a planning tool. Keeping all of your work that needs doing on dedicated lists makes sense. But keeping all your important dates about projects in separate folders instead of on one calendar seems a bit loony. Why wouldn't you want to see all of your due dates at once? Why shouldn't you plan the day and times that you want to work on something, even if it doesn't HAVE TO be done that day? While I like the whole process of capturing and clarifying I still need a plan for doing and I'm usually juggling multiple projects. I fundamentally don't see why your calendar shouldn't be part of your daily and weekly planning.
