This is a calendar, located on the side of a church in Colmar, France. See the black shadow? That is the marker for determining the month. If you zoom in, you can see that it is lying between March and April, but leaning slightly towards April. Today was March 19. It works! We need to get one of these for the
planetarium in Chapel Hill and place it near the sundial. We also need a tip jar, or at least a cut from the
gravity well, but that is a different matter.
