…and it involves some ideas I’ve accumulated over the years.

Getting facts and dates straight in a narrative matters. You bet readers notice. Maps. Floor plans. You need these things.

I keep a nice little Laurel Burch book OSG gave me some time ago which is my notebook particularly for the Foreigner books. And that lets me keep track.

One of my discoveries is the value of old calendars. Or just doing a calendar form in your word processor and plugging it in. The combination of a detailed outline with a calendar, or an outline ON a calendar, is a very good way to keep things straight. When there’s a calendar, you’re not going to have things that aren’t set up, (a note several days prior), and you know where various people are at the time, which can suggest ideas, or at least make it sound as if you actually know what you’re doing. Can’t recommend it enough. Just jot notes down in the date squares, and tie it to the outline, and you will not later discover you have things in there twice (this can happen when you go to a convention and come back convinced you haven’t mentioned something but have) or that you’ve forgotten to do a set-up for something that happens, say, on the 15th of said month. It doesn’t matter that months may not have the same number of days: you don’t have to go crazy—just get the sequence right. This also helps you in fantasy stories where moon-phase may govern who can see what at night (no few fantasy writers are guilty of a perpetually full moon, which is the devil to explain).

It’s all part of that internal consistency thing.
