Abstract (en)
[origin: EP0634711A1] The annual calendar mechanism includes a calendar-entraining wheel (18) fitted with a finger (17) capable of entraining a calendar wheel (19) one notch at the end of each month. An annual wheel (25), entrained two notches once a month by a long tooth (23) carried by an intermediate wheel (21) itself enmeshing with the calendar wheel (19), includes a plate (27) carrying five teeth (28). If one of these five teeth, corresponding to one of the months with fewer than thirty-one days, shows up in the path of the finger (17), the annual wheel (25), from being driven becomes driving and entrains, via the intermediate wheel, the calendar wheel an extra notch. <IMAGE>
