A calendar display device for a mechanical watch piece including a first disk, the disk of days, carrying multiple series of inscriptions symbolizing the seven days of the week, a second disk, the disk of dates, carrying inscriptions symbolizing the date of the month, a third disk, the disk of months, carrying 12 inscriptions symbolizing the months of the year. One of the disk of days and the disk of dates acts as a dial by being fixed, whereas the other acts as a rotary disk by being arranged concentrically and rotatably in relation to the dial. The dial includes an aperture making it possible to see the inscription of the current month on the disk of months. A hand indicates simultaneously the date and the day of the week. The device includes a correction mechanism cooperating at least with a gear train bidirectionally driving the disk of months.
