Abstract

An improved calendar, characterized by comprising three elements consisting of a base disk which superiorly and peripherally carries the months grouped into seven squares created by a plurality of radii that converge in the geometric center of an ideal outer circumference, while in the lower part opponent are organized as many radial divisions of equal convergence, which from left to right and from lowest to highest contain the representative digits of the 31 days of the month, forming rows and columns of easy and quick visualization; a second disk, rotationally movable, where a series of years and weeks are placed circularly, the first in outer circumference from least to greatest and from left to right, forming groups of four with intercalation of the leap years, the latter with identifying signs, accompanied by some isolated year, which the combinatorial period requires, and a second inner circle concentric with the outside, where complete series of days of the week are represented, in such a way that their positional coincidence responds to the conditions imposed by the law mathematics on which the calendar is based, which is completed with a third disk, depending on the outer cover, provided with two windows that allow quick visualization of the year and day of the week in question.
