ONLY holds one schedule. This is not a big deal because you can import and export schedules as needed. This means you can create a 1/2 day schedule, export it, a normal day schedule, export it and then be able to just import the schedule as needed replacing the old one.

How to Modify the Bells Schedule

Go to the server at: https://ctebells.ccisd.adremc1.org
Log in with user: admin and the admin password
Click on the Schedules button on the top row of menu buttons
To save the current schedule scroll to the bottom and select Export schedule. Save it on your computer so that later you can re-upload it if you need. This way you can have many schedules saved to your machine and just re-upload them (import them) to change bell schedules quickly.
Here you can create new bell events, edit existing events or delete bell events
