Abstract
In an annual or perpetual calendar mechanism, a lever bears a maneuvering device of a day-of-the-month wheel. A month wheel defines course beginning stops, each associated with a month and operational for controlling a course beginning position of the lever when the month wheel is in the angular position associated with this month. These course beginning stops are bottoms of slots alternating with the teeth of the month wheel. The month wheel has a peripheral edge which forms the profile of its teeth as well as the course beginning stops.
