Fixed Asset Calendar setup for GP 2015

Do I have a create a 2016 calendar if I am implementing Fixed Assets as of Jan 1 2017?  

I intend to use Dec 31 2016 as the "Depreciated to Date" on the BOOK as my client was using a third party FA product.  

Must I have a 2016 calendar setup?  Perhaps I use January 1 2017 as the "Depreciated to Date?

Just not sure if putting Dec 31 2016 on the BOOK is a problem when there is no 2016 set up.

Thank you!
