Timepiece calendar system

Abstract

The timepiece calendar system (200) includes a date mobile (4) displaceable step by step relative to a frame (199); a first drive finger (21) for driving the date mobile (4); a first tooth (51) for driving the date mobile (4), the first tooth (51) being mounted on the date mobile (4) so as to be displaceable between a deactivated, or retracted, position and an activated, or drive, position; an activation system (6, 7) for activating the first tooth (51); the first drive finger (21) and the first tooth (51) being arranged such that a single action of the first drive finger (21) on the first tooth (51) displaces the date mobile (4) through n steps, with n being an integer of any value between 1 and N, N being an integer with N>1, depending on the moment when the first tooth (51) is activated by the activation system (6, 7).
