ABSTRACT:
A desk calendar which permits the day, date and year to be changed by the simple manipulation of two dials, having, internally, a first and second shaft, each shaft controlling two rotatable drums. Each shaft has disposed thereon a first and second actuating member for operative engagement with a coupling device such that when the dialing member is turned in one direction the first drum will rotate and when the dial member is turned in the opposite direction the second drum will rotate. The same structure is related to the second shaft which is disposed on the other end of the frame having a separate dialing member associated therewith.
