The calendar visualizes time by showing the remaining weeks to the end of the year, month-by-month. The 52 weeks of the year are represented by holes that were die-cut and continuously disappear by month. December ends up with 4 holes. Each month features a different high quality, colored paper by Fedrigoni. Hansen/2 created and designed the three-dimensional DIN A5 calendar, which deals with time as simple data in an easy and playful way.
