Disclosed is a date indication device with an annual calendar function, said device having the following elements: a drive wheel (8) coupled to a mechanical movement; a driving device which is driven by the drive wheel (8); a date wheel (4) which periodically interacts with the driving device and is driven thereby; a month wheel (5) which in turn periodically interacts with the date wheel; and a month cam disk (6) which is connected to the month wheel. The driving device has a driver (8.1) and an axis of rotation (8.3), wherein the driver moves about the axis of rotation (8.3) of the driving device on a path and the axis of rotation assumes at least two different positions relative to the date wheel (4), wherein in a first position, the driving device advances the date wheel by one unit and, in a second position, by a plurality of units, and the assumed position depends on the number of days of the respective month. |
