Calender in form of dodecahedron - has days of month arranged as digits along five edges with Mondays or Sundays in corners of each of the twelve side surfaces

摘要

The days of a month are so arranged along the periphery of a five-sided surface that each edge contains the days of a week, with the Mondays or Sundays actually in the corners of the surface. The figures are arranged along an imaginary line, which runs parallel to the edge of the five-sided surface from which they are spaced by a distance corresp. to the figure height. The five-sided figure with the dates of a month shows the edge with the days of the last week of the month. This edge is common to the five-sided figure for the following month. ADVANTAGE - An improvement on known pentagon-dodecahedron type calenders which are not always easy to read.
