Perpetual calendar characterized because it is made up of a box that can be mounted on a support provided with three windows designed to show the months the numbers of the days and the days of each week, behind each one a set of two rollers ends geared to which and on a plate is supported and slides the band of paper that has printed the corresponding data (month number of the day and day of the week) so that maneuvering a lever can run the band out of a roller and coiling in the other and vice versa when it is necessary to begin again, retracing the referred data.
