I read books on a schedule so I needed a quick way to create tasks for how much to read in a day. This script adds these tasks automatically after asking a handful of questions about the book and your timeframe. You can learn more about it here.
You'll want to update the beginning line of the script with your Context of choice. If you don't and "Read" is not an available context, it will throw an error.
The default date format is set to "mmddyyyy". If your system uses "ddmmyyyy", please modify the second line of the script.
Also, if you want an iOS version of this script and you have Workflow for iOS, check this out.
You'll find two versions of the script - .scpt and .applescript. In order to run it from OmniFocus, you'll want to use the .scpt version. The .applescript format is purely there so you can view the code online.
I'm certainly open to the submission of Pull Requests to make this better. If you find issues and fix them, please let me know and I'll be happy to update and give you credit.
