Abstract
A first mechanism (2, 5, 8, 18, 20) of the calendar drives a date indicator, bearing numbers 1 to 30, by one one-day step at the end of each day, off a rotary part (1) of an analog timepiece movement. A second mechanism (60, 62) causes the date indicator, in cooperation with the first mechanism, to move forward from the 29th to the 1st of the following month at the end of the even months. A third mechanism (75, 79, 95, 97) inhibits the action of the second mechanism at the end of the embolismic (or abundant) years whereby at the twelfth and final month of these years the date indicator displays 30 before proceeding to the 1st. The calendar is perpetual, and a date-corrector (11) and a month-corrector (54) enable the calendar to be updated.
