An Apple a Day Calendar

Here is a different looking calendar that should be of interest. The calendar tells you the day and date each time you offer an apple per day. Just fill the calendar every month with the number of days in that month, and adjust the numbered calendar behind the transparent tube. Eat an apple each day and watch the calendar advance.

This calendar is a brainchild of the Serviceplan advertising agency of Munich, Germany.
