Calendars are intrinsically interactive on a personal, individual level - you enter appointments, check dates, plan the future and revisit the past, all of which are keyed to your life and how it intersects with the lives of others. The Open Day Book serves as a perpetual calendar that can be used in a traditional manner, but also lets you interact with the work of more than 300 of today's most captivating artists, all of whom have visually responded to a day of the year.

The design of every dated page allows users to fill in their schedule or respond artistically to the work on the page, engaging with the artists and their work. The over 300 contributing artists have all created work especially for this book that is designed to be used as a daily journal, sketch book or admired as an art book.
