Zusammenfassung:	The mechanism has a mobile month drive (52) provided for driving a month star (54) at the end of each month. The drive is connected to a mobile date drive (32) and mobile correction drive (42) via driving wheels (36, 56). The drive (52) occupies a position, in which the drive (52) has no effect on the star such that a kinematic chain between a date disk and the star is broken, and another position, during changing of the month, in which the drive (52) activates the star to advance the star to a step such that a correction device acts on the date disk without affecting the star and vice versa.
