JIGSAW PUZZLE PERPETUAL CALENDAR

摘要

A jigsaw puzzle perpetual calendar includes a pattern assembly (20) and a calendar assembly (30) mosaiced in an outer frame assembly (10). Every pattern piece (21) of the pattern assembly (20) can be put together to form an integrated pattern. The calendar pieces (31) of the calendar assembly (30) have the same contour. The position and the positive/negative side of the calendar pieces (31) can be exchanged in anyway to make up the corresponding month. Thus the calendar can be used perpetually and needn't to be replaced, so as to save cost.
