Calendar 2016

As some of you might know I am making handmade book binding and I am trying to make a book-calendar each year. I am already starting to think about the 2016 one to be in good time, but I would like some feedback!

I give out one free 2016 book calendar to someone between all the answers I get here, on facebook and my deviantArt!

I would like to know if you would prefer one week per page or one day per page or 2-4 days per page?

OR if you already have one of my books or calendars - what can I do better?
OR if you are a calendar freak - is there a cool feature I should add to my calendar?

Thank you for your feedback!
Every answer will be in the draw for the free book calendar!
