Astronomical Clocks – Literally and Metaphorically

The term astronomical clock is one that is used fairly loosely. Effectively any clock that shows astronomical information – as well as the time – can be so classified. They can show the location of the sun in the sky, for example. In addition to that they can show the position of the moon – and further information such as its phase and its age. Others go further and show the current sign of the zodiac or even go as far as showing a rotating map of the stars.
