The sheet is mounted in a support 1 having ribs 6 which, for each row of indicia, define a corresponding channel 7 in which a plate 8 slides. The plates are moved to their desired positions by an external magnet 5, unused plates being kept behind an opaque region of sheet 1. The calendar may be a wall or desk calendar.
