Abstract

The invention relates to a mechanical perpetual calendar with month display, including: a) a day number matrix (2) of seven lines and four columns grouping, by groups of seven, the first twenty-eight day numbers of each month in increasing order, each group corresponding to a week of the month, and a fifth column including three openings (3, 4, 5) that correspond to the variable day numbers twenty-nine, thirty and thirty-one; b) means for displaying the variable day numbers (23, 22a) of a determined month and presenting in said locations (3, 4, 5) the last two or three day numbers of said month; and c) a mechanism (11, 13, 12, 28) for controlling the display means of the variable day numbers.
