ABSTRACT:
A perpetual symbol coded means for calendaring, presenting--in one embodiment--a two dimensional matrix which graphically presents the basic information of the month, day and date for a given year. Correlation of the basic calendaring data is achieved by way of a matrix, whereby a column arrays monthly data, another columnar arrangement offers day information for consideration and a yearly designator appears as a legend or heading. A method of use, including a means for extrapolation of any desired yearly information into the present invention is taught in addition to software means for implementing the same.
