For a few years, I evolved a slightly-modified Todo.txt format for this purpose, to represent both tasks and appointments. http://todotxt.org/ http://todotxt.org/ https://www.neilvandyke.org/todotxt/ https://www.neilvandyke.org/todotxt/ In some ways it worked well, but there were a few drawbacks, and eventually I switched to native calendar programs on desktop and mobile. Drawbacks I personally felt: * In the text file, recurring tasks didn't show up when I looked into the future, such as to schedule an appointment. * Calendar invites over email weren't integrated, so I had to enter and update those manually anyway. (Though one advantage over the native calendar programs I use now is that todo.txt doesn't force the appointment headline someone else wrote into my calendar view, and refuse to let me edit it in my local copy.) * I had to keep editing dates on tasks manually, every day, for my "current day view" of top of the file to work with priorities. * No visual calendar views with the tools I was using. * No device sync with the tools I was using (though possible). * There are only so many ways in which I was willing to be a weirdo at once, and this one didn't make the cut. I don't discourage anyone from trying todo.txt or calendar.txt. Just a heads-up of some things you might want to find solutions/workarounds for.
