A wall calendar is a calendar intended for placement on a wall. 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.
Common subjects include landscapes, automobiles, wildlife, male or female models (often suggestively posed, sometimes nude), and popular culture. Sizes of wall calendars vary, with 12 inches by 12 inches (305 mm by 305 mm)(closed) being a typical size within the United States.
Businesses frequently give wall calendars branded with their names and contact information away for free to customers as promotional merchandise.
