How do I hang a Japanese calendar? - metal calendar wheel

I just got a calendar for 2006 very Domo-kun as a Christmas gift, but I'm at a loss as to hang. There is a metal strip that contains the calendar of meetings in the lead, with an "eye" fixed on the wall - but I do not see life as it is the sides?

Currently, I think it's likely each page carefully, as you progress through the years to cut, but I'd rather not until I am sure there is no other choice.
