PROBLEM TO BE SOLVED: To provide a calendar displaying/moving apparatus for eliminating a risk due to an instantaneous jump drive mechanism for driving a plurality of steps. SOLUTION: The calendar displaying/moving apparatus includes a calendar moving apparatus 1, a driving/moving apparatus 3, an instantaneous jump cam 7, and a finger 9b kinematically coupled to the instantaneous jump cam 7. The drive finger 9b is supported by a release member 9 swingably attached around shafts 6, 7a. The shaft 6 is a shaft of the driving/moving apparatus 3. The release member 9 has an opening 9a configured so as to enable an angular displacement around the shaft 7a. While a calendar is corrected, the drive finger 9b is released from teeth 1a of the calendar moving apparatus 1. A return spring 8 rotates the drive finger 9b around the second swivel shaft 7a, and guides an end of the opening 9a so as to abut on a hub 3a as a position in which the drive finger is engaged with the teeth of the calendar moving apparatus 1.
