Abstract
Perpetual calendar, characterized by the fact that on a ruler folded in four folds, two buttons are threaded with their free center and by means of rear clips that allow and admit these two buttons to slide along the straight parts of the ruler and even save the curved connecting elbows to pass to the contiguous straight zone with which there are two markings corresponding to the days of the week and the days of the month.

Geometric or crystalographic, complete or schematized figures that, integrated in a single piece, are simultaneously visible. (Machine-translation by Google Translate, not legally binding)
