A calendar date display comprises a ten-day pointer (2) and a unit pointer (1) driven by a program drive (8), which is provided with a calendar date display (9) whose toothing is engaged with the nose (15) of a lever (16) in such a way that a wheel is moved one step forward by one calendar number change. Between each calendar number change, the nose (15) is engaged between the first and second teeth (11, 12) of the wheel (9). At the time of the calendar number change, the nose (15) is disengaged from said first and second teeth (11, 12) in such a way that it is engaged between the second and third (12, 13) teeth of the wheel (9), thereby moving said wheel one step forward. |
