A method for forming a date indicator actuated by a clock movement to show, in succession and automatically, all the days from 01.03 of one year to 28.02 of the next year, wherein the units and tens numerals arc placed onto respective indicator runners comprising ten numerals or a multiple of ten, and four numerals or a multiple of four numerals, respectively, two drivelines are formed, one being a daily driveline between said clock movement and said indicator runners, for moving the unites indicator runner selectively step by step by one step every 24 hours, and for moving the tens indictor runner by one step for every ten steps of the units indicator runner, in order to move on from one multiple of ten to the next, and for moving said tens indicator alone by one step to move on from “31” to “01” on a 31-day basic cycle, and an annual driveline between said clock movement and said tens indictor runner, which driveline is programmed to move the tens indicator runner by one step at the same time as the units indicator runner is moved by the daily driveline, to move on from “30” to “01” at the end of the months which comprise less than 31 days.
