An upper disk has a circular periphery with a notch along a portion thereof, andfurther has a cut-out spaced uniformly from the periphery and extending along a portionof the periphery. Numeric indicia are printed on the upper disk adjacent the notch. Thenumeric indicia are sequential numbers from 1 to 31 representing the thirty-one days of acalendar month. Month indicia are printed on the upper disk in a predetermined patternadjacent the cut- out. A lower disk has week day indicia printed thereon uniformly spacedalong the periphery thereof, in a sequential pattern. Spaced inwardly from the week dayindicia is a predetermined pattern of year indicia indicating each year from the firstthrough the second preselected years, inclusive. The position of the year indicia is such asto show through the cut-out, and the position of the week day indicia is such as to showthrough the notch. Alignment of a month indicia with a year indicia automatically indicatesthe days of the week for dates in that month in that year.
