Limit NEXT/PREV Date in Appointments Schedule Pagination

I will be launching a site soon that will allow visitors to "Reserve" any hour within the year 2015. The temp reserve page is

I've noticed a couple of problems that I am having while setting up this page.

1. I want the visitor to browse through the entire year of 2015. I have the calendar starting at Jan. 1, 2015 but it only advances 365 days from the Current Date (today). I know where that setting is but I don't want to change that since I only want the visitor to view 2015.

2. I think these issues are connected, but I also don't want the visitor to navigate back to any date within 2014 (it won't be necessary and possibly confusing). How can I limit the Appointments calendar to 2015 only?

Please advise. Thanks,
