A plurimillenary universal calendar comprising a support carrying one or more symbol scales for time periods, as well as a plurality of members slidable relative to the support, on each of which are placed one or more scales of other symbols of time periods, wherein each scale comprises subdivisions which are geometrically equal to one another and to those on the other scales, and being the calendar structurally set on the basis of an ideal year beginning on March 1st and ending on February 28th or 29th, on its scale each symbol is spaced apart from the chronologically preceding symbol by as many subdivisions as the week days passing between the beginnings of the two time periods to which said symbols are related.
