The Rollbahn series introduces a "free" diary with an open dating system. The month and date fields are blank, so you can start using it whenever you like.  There are 12 months of monthly pages, 1 year of weekly pages, 72 pages of Rollbahn grid and the usual Rollbahn clear pockets at the back.

Opening the cover reveals one inner cover page for writing the title, start date, and goal setting; one free-form to-do list page; one accordion-style calendar page for filling in the entire year; one standalone page; a two-page spread for writing the month and date, totaling 12 months; and two block-type weekly pages, each with eight days per spread, for a total of approximately 52 weeks. The back of the book contains 72 grid memo pages and five convenient clear pockets. This book is recommended for organizing to-do lists, life logs, and daily schedule management.
