Circular calendar

A whole year on one poster. Since 2018, the same principle every year – and a new theme at the center each time. From the constellations to the moon to the Alps.

Why a circle?

With our calendars, we want to depict the entire year on a single poster. For us, the circle is the ideal shape for this: a year can be represented here as a self-contained, closed section.

The circle is also a fitting symbol for the recurring cycles we experience every year. A year corresponds to the time the Earth needs for one orbit around the sun. After one year, the Earth is once again in the same position relative to the sun. The sequence of seasons, holidays, and celebrations likewise repeats every year – like a cycle.

The structure: ring by ring

The calendar is built from a series of rings around the inner circle. From the outside in, they show:

  • 1. Personal notes & holidays
    A large field for each day – with the public holidays in Germany, Austria, and Switzerland.
  • 2. Three marking rings
    For your own graphic markings: sports, trips to the cinema or theater, a personal period of fasting – whatever you want to keep track of.
  • 3. Date & weekdays
    Every day of the year, laid out in a circle.
  • 4. Calendar weeks
    Weeks 1 to 52 at a glance.
  • 5. Months
    The twelve months as segments of the year.
  • 6. Moon phases
    The lunar cycle across the entire year.
  • 7. The year's theme at the center
    A large infographic – a different theme every year.

Your personal year infographic

A large field for each day offers room for personal entries: birthdays and other celebrations, appointments, the ski trip, the next cycling trip, or hiking tour. Three additional rings are there for graphic markings – sporting activities, trips to the cinema or theater, a personal period of fasting.

By the end of the year, this gives you a quick, infographic-style overview of your very own personal year. A calendar that becomes a retrospective.

A calendar that stays

All circular calendars are offset-printed on matte paper in a 60 × 60 cm format – large enough for an entire year on the wall, and beautiful enough to stay hanging afterward.
