Abstract
Abstract Incorporating for the first time in a perpetual calendar the concept of separating the two digits of the "year," into a single DEACDE digit plus a single YEAR digit, this device determines the calendar for any desired century, decade, year and month whatever, by positioning these calendric time units in combination with each other in successive chain-like liaison, automatically revealing, as a result, the correct calendar desired. It consists of a number of components, each comprising one or more indicia-group-bearing and viewing-area-embracing means or elements (of whatever kind, style or nature), each of which consists either or an indicia-group region and a viewing-area (fenestella, arrow, or the like) region, or of two indicia-group regions. The desired century can, in a given calendar, be displayed in only one way; this determines the only single way in which the desired decade can then be displayed, this positioning, in turn, determining uniquely the spatial setting of the desired year, and so on. Only one such specific designation is displayed at any one time, and it is displayed in full! This unequivocal and unique sequential setting and display and, consequent, automatic calendar revelation are achieved by providing differentially restricted viewing areas, and numerals and month names all correctly positioned with respect to each other on such means, in strict accordance with the hebdomadal sequence patterns fundamental to, and inherent in, the several kinds of time units necessarily involved in the Gregorian (and/or Julian) calendar formulas.

Claim 1
Independent Claim
212 words
A perpetual calendar comprising, in combination: means for exhibiting a first viewing area; means for selectively displaying, at such first viewing area, indicia designating a numeral consisting of at least one digit representative of a century; means for the positioning, responsively to such selectively displayed century-designating indicia, of a second viewing area; means for selectively displaying, at such second viewing area, indicia designating a numeral consisting of one digit representative of a decade; means for the positioning, responsively to such selectively displayed decade-designating indicia, of a third viewing area; means for selectively displaying, at such third viewing area, indicia designating a numeral consisting of one digit representative of a year; means for the positioning, responsively to such selectively displayed year-designating indicia, of a fourth viewing area; means for selectively displaying, at such fourth viewing area, indicia specifying a designation representative of a calendar period of time constituting a part of a year consisting of at least one month; means for exhibiting a fifth viewing area; means for resultingly displaying, at such fifth viewing area, and responsively to such selectively displayed partial-year-specifying indicia, indicia constituting, in correlation vis-a-vis the days of the week, the corresponding dates of the calendric period designated by the thus successively, selectively displayed century-representing, decade-representing, year-representing, and partial-year-period-representing indicia.
