Abstract: A single and/or continuing event calendar which particularly lends itself to computer print-out. The calendar is in the form of defined rectangular spaces arrayed in the manner of a conventional monthly calendar with the definition of the spaces accomplished both vertically and horizontally by a series of dash lines spaced from each other, but with the horizontal lines defining each space being interrupted by the name of the day and the date applicable to such space. The calendar provides desired information in summary form concerning a plurality of single and/or continuing events in a given field of interest and which may occur concurrently and/or sequentially during the period of a particular month (or any part thereof).
