The perpetual calendar includes 12 Nins® in 12 colours according to the Waldorf tradition, both to determine the month and its season of the year. One natural beech wood bowl, two natural beech wood cubes with the numbers of the days printed, and a platform in 4 sections that determine the seasons, stamped with the months of the year. Perpetual calendars allow children to touch the year and understand the passage of time through the experience. They help little ones to learn about the seasons and can be combined with natural materials from the outdoors as the seasons change.
