A calendar, characterized by comprising a pedestal on which a support element to which a permanent magnet is fixed is placed between groups of plates of magnetizable material, suspended through corresponding threads, of respective elements of support also fixed to the base; all in such a way that it suffices to sufficiently approximate one of these plates to the magnet so that it remains balanced -suspended in an apparently unstable position- between the magnetic force of attraction developed by the magnet, and the reaction that keeps the thread tense.
