You can start planning with the "Manager" at any time and always have an overview of the full 12 months ahead of you. Expired dates from a month are deleted and can be rescheduled for the next year. With printed weekdays and annually movable, magnetically adhesive calendar strips (from 1-31), the planner can be used year after year. The calendar strips must be ordered separately or are included in the extensive accessory set for the "Manager.".
