A month cam (25), which is mounted so as to pivot freely concentrically with the date mobile (19) is designed to turn through a twelfth of a turn for each turn carried out by the date mobile. The date mobile bears a lever (27) provided with a forward-driving tooth (29) and a rearward-driving tooth (31), the lever being designed to take up either an active position or an inactive position depending on the angular position of the month cam (25), the forward-driving tooth (29) being designed to be located on the path of the second finger (17) of the drive mobile (13) when the lever (27) is in the active position and the calendar mechanism is displaying "30", and the rearward-driving tooth (31) being designed to be located on the path of the second finger (17) of the drive mobile (13) when the lever (27) is in the active position and the calendar mechanism is displaying "31".
