Changing calendar code

I need someone to modify the example number 2 from this website: [login to view URL] I want the time to be a range ("From:", "To:") that applies to the day or days selected. When someone hits "Apply" I want to create an entry in a database table with the day and time range selected. And to change the background color of a day if it exists an entry in the DB. Must provide a migration to create the table in the DB and must be Ruby on Rails. I'll provide more details.
