The invention relates to calendar mechanism for a clockwork. Conventional calendar mechanisms, especially modular mechanisms, that are mounted on clockworks, especially those in the form of an eternal calendar, are driven by the clock via a wheel which comes full circle in 24 hours. The time is indicated separately in units and tens via a printed toothed display disc, and a program carrier comes full circle in 31 days. According to the invention, said program carrier (4) controls additional locking elements (13, 19) in such a manner that on those days where there is a danger of the display discs advancing too far, the locking elements can be swiveled into and out of the rotational movement of the display discs (2, 3), thereby preventing the display discs (2, 3) from advancing too far by an interaction with the toothings (9, 16).
