Create Schedule from Calendar Data

Hey everyone, I've got some data based on a short term class schedule. I'd like to figure out a way to turn this data into a calendar format in excel, where the date, start time, and duration of the class automatically create a window to be blocked off on the calendar so no other class can accidentally be scheduled there. It's easy enough to do manually, but this is just a small example of the schedule, which is really about 20 times the scale. Also, when I change the data in Cell A2, I'd like the calendar to update to show that day.

Any suggestions?

Thanks!!
Justin
