im having difficulty understanding how the complex date input works and would appreciate any help.

What i want is to schedule a class i teach on a sunday from 09:00 to 11:00 between 3/6/2016 to 1/7/2016

from what i can understand i need to use sexp syntax and found and example online but this is how far i got:

even this example that dosent take hours into account dosent appear in my agenda.

Can anyone give me an example that includes hours and show me how to make it appear on the agenda?

best!
