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.

In an annual or perpetual calendar mechanism, a day-of-the-month wheel includes a notch. At each actuation of a lever, a first pawl finger effects an actuation of one step, on one of the teeth of the day-of-the-month wheel. Upon actuation of the lever at the end of a month of fewer than 31 days, a second pawl finger effects, in the notch, an actuation of the day-of-the-month wheel by a whole number of steps. The notch is positioned between two consecutive teeth among the teeth of the day-of-the-month wheel. The day-of-the-month wheel has a peripheral edge which forms the profiles of its teeth as well as the notch.
