I answered Vanessa via separate email, but for anyone else who may have the same question:
All you have to do is create another school year for 2014-2015. Go to Admin > School Years > Add New, then set your dates. We do have a reference calendar on the Mac version, but not on the iPad version, so it will help to have another calendar nearby when you decide on your beginning/ending dates, holidays, etc.
Just remember that in the Assignment Calendar and Today views, you will only see the calendar for the ACTIVE school year. So, if you want to work in next year or a previous year, just go to the School Year section, choose the correct year and "Set Active."
