You Tube Channel – Hanging On His Words – has featured this calendar in one of its many excellent videos.
The working calendar can be seen at time – 1:12:22 but why do that when you can watch a truly edifying video on calendar history presented with superb clarity?
Many more great Hanging on His Words video presentations can be found on the You Tube Channel.
My rather poor attempt at filming the calendar in operation, but with a better close up view, perhaps I can inspire you to start making your own calendar?
