"Wall calendars can serve as reminders of holidays, important events, and company events. They typically consist of a collection of images (one per month) on a given subject.
Example subjects include automobiles, wildlife, male or female models, etc." [Wall calendar. Wikipedia]
The month calendar sample was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Calendars solution from the Management area of ConceptDraw Solution Park.
