This is a simple script that converts Schedule Builder (CUNY) courses to ICS format so you can easily import them into your calendar. It includes the course name, time, location, and teachers. This script does not take holidays into account yet.
- Go to the Schedule Builder page with your courses for the semester.
- Inspect element (right click and select Inspect) and click on the Console tab (located by default on the top right).
- Copy the script below (source code is in
script.js, you should always be cautious of running scripts in your browser and verify it is safe). - Paste the script into the browser console and hit enter. This will download a file called
class_schedule.icscontaining your schedule. - Upload the file to your calendar.
