In Norway we have several names for this type of calendar: Skiftplan, skiftkalender, rotasjonskalender, offshorekalender and rotasjonsplanlegging. All of them present a typical website calendar which is good for printing out at home or office.

This kind of printouts require some labour, from your side 🙂
Find your scissors and cut out the calendars, flip vertical together and glue together.
Laminate the paper to ensure it withhold normal usage in wallet.
