Abstract An adjustable calendar for automatically designating the relationship of a repetitive or non-repetitive non-conventional time cycle to a conventional time cycle for a given day. The calendar includes a base having a predetermined calendar period imprinted thereon. A transparent overlay sheet is adapted to be removably affixed to the base. Indexing means are on the base and said overlay sheet for alignment thereof in a predetermined manner. A curve is imprinted on one of the base on the sheet to indicate the non-conventional time cycle of a repetitive or nonrepetitive sequence of events on a continuous basis. A conventional time line is on the other of the base and the sheet positioned so that when the overlay sheet is properly aligned with the base, the conventional time line will be aligned with the curve in a predetermined manner. Finally, lateral adjustment means are on the calendar to shift the sheet with respect to the base to a desired position so that the conventional time line is aligned with the curve to designate a known relationship between the non-conventional time cycle and the conventional time line for a particular day thereby automatically defining the relationship therebetween for the remainder of the days in the remaining calendar period.

An adjustable tide calendar comprising: an elongated rectangular base formed in layers with each layer having daily successive calendar markings for a period in excess of one month and the layers arranged in monthly order; each layer having a curve thereon in alignment with the associated calendar markings and representing daily tidal conditions for a given geographic area; a transparent overlay sheet adapted to be removably affixed to the base; an array of time lines on the overlay sheet and calendar indicia arranged for alignment with the markings and curve on each base layer; indexing means on the overlay and each base layer to facilitate proper positioning of the overlay with the exposed layer of the base whereby when the overlay is properly positioned on the exposed layer for a tide condition at one point in time the tide conditions will be automatically designated for the entire period in excess of one month and the portion in excess of one month coinciding with the beginning portion of the following month on the next succeeding layer so that as each layer is removed the overlay can be properly aligned with the next layer for continuously providing tidal conditions for the given geographic area; a resilient releasable clamp for holding the overlay sheet in tight interengagement with the base and in alignment with the exposed layer of the base to designate tidal conditions for the period in excess of one month; the clamp being a U-shaped elongated resilient member with opposing sides tending to move into engagement; and the base and overlay being extendible between the sides so that the sides place a compressive force thereon to hold the base and sheet together as the sides attempt to engage with one another, and the base and overlay being shiftable with respect to one another and separable for removal of base layers by forcing the resilient sides away from one another to free the overlay and base.
