I've been making a better effort to use my calendar more for date specific tasks instead of the due date field in tasks. It not only seems to keep my mind on what to do at specific times, but it has the side effect of being a kind of journal of what happened when.
My question is this: when I use the calendar for a time-specific task (ex. to call someone on a certain day and time), should I also place it into my tasks list under @Phone? Or, is that double entry and possibly a bad idea, since I may lose track of my action? (I know that GTD can be flexible about things, but I wanted to ask people with more experience in this what they tend to do). Thanks!
