Perpetual Calendar Puzzle

This puzzle is a perpetual calendar that is based on a Rubik’s Cube, but only one face of the cube is solved each day. The puzzle is stored in its original packaging, a cardboard box, and is wrapped in plastic so the original date, Saturday January first, is maintained.
On the face of the cube that represents the day, the top row displays the day of the week ((Satur)(day)( )), the middle row displays the month ((J)(A)(N)), and the bottom row displays the day of the month (( )( )(1)). The box also contains a black plastic stand for display and instructions.
This puzzle was made in Korea and packed in the United States in about 1982. It is among Rubik’s Cube related items from the Cube Museum, which operated in Grand Junction, Colorado, from 1988 to 1991. For more information about the Rubik’s Cube and other twisting puzzles that use the same or similar mechanisms see 1987.0805.01.
