ABSTRACT:
A perpetual monthly calendar for showing the numerical days of any month related to the proper days of the week comprising a rigid planar surface having a plurality of pegs spaced apart in a horizontal line disposed near the upper edge of the surface and a plurality of vertically positionable rigid strips bearing columnized numerical indicia indicative of particular numerical days, each strip removeably coupled to a different peg. Displayed on the planar surface adjacent each peg are indicia correlating a particular peg to a particular day of the week. The numerical indicia on each strip is displayed in column form, displaying the appropriate numbered sequence one week apart. Each strip has a pair of vertically disposed apertures (except the strip having the first day of the month, which has a single aperture), each of which may receive a peg to mount the strips vertically on the board. A particular monthly numeral-day array is achieved by positioning the strips relative to the pegs.
