## Title
Three-view foldable calendar

## Abstract

A three-view foldable calendar (10) consisting of a single integrated structure (12) that includes three sections: an upper section (14), a center section (16) and a lower section (18). When the calendar (10) is to be stored or mailed, the upper section (14) and the lower section (18) are folded over the center section (16) to allow a small compact structure to be formed. The upper section (14) has adjacent an upper edge (24) a centered hanging hole (36) into which is inserted a pin that secures the calendar (10) to a wall. When the calendar (10) is placed in a viewing configuration it is hung on the wall which allows three consecutive calendars months to be displayed for comparative viewing.

## Background
TECHNICAL FIELD
The invention pertains to the general field of wall-hanging calendars and more particularly to a wall-hanging calendar that allows three consecutive months to be displayed and that can be compactively folded for storage or mailing.
BACKGROUND ART
The use of prior art calendars can be traced from the Julian calendar which was in use around 40 B.C. to the Gregorian calendar that was adopted in the U.S. in 1752 and is now in common use throughout the world. Most of the prior art calendars are designed to display one month at a time. In less common use are calendars that display two or three calendar months. The prior art calendars that display three consecutive months are generally difficult to fold into a package that will not crease the display surface of the calendar. Also, they are typically not dimensioned to be folded into a compact package that is easily mailed.
The instant triple-view foldable calendar solves the creasing and folding problems prevalent in the prior art by having three equally dimensioned, articulated sections: an upper section, a center section and a lower section. The upper and lower sections fold inward into the center section to form a compact, flat package that will not crease the monthly display and that is suitable for mailing. The three articulated sections are easily extended to allow three consecutive months to be viewed.
A search of the prior art did not disclose any literature or patents that read directly on the claims of the instant invention.
DISCLOSURE OF THE INVENTION
The three-view foldable calendar is designed to be folded into a compact package during storage or mailing and in a three-view viewing configuration that allows three consecutive months to be displayed.
The calendar is comprised of three sections: an upper section, a center section and a lower section. The upper section has twelve pages wherein each page has an upper edge and a lower edge. The center section consists of only one page having an upper edge and a lower edge. The upper edge of the center section is foldably attached to the lower edge of the upper section preferably by a spiral fastener. The lower section also has twelve pages wherein each page has an upper edge and a lower edge.
