Abstract
The calendar mechanism includes a 31 wheel set () for controlling a date indicator, a date drive means for driving the 31 wheel set, a 12 wheel set () for controlling a month indicator, and a monthly drive means for driving the 12 wheel set at the end of each month. The monthly drive means is activated by the 31 wheel set during the change from the end of one month to the first day of the next month. The calendar mechanism further includes a manually activated month corrector device arranged to advance the 31 wheel set in one stroke to an angular position corresponding to the indication of the first day of the next month, so that the monthly drive means, activated by the change from one month to the next, increments the 12 wheel set by one step.
