Lunar Calendar
Knowing the phases of the moon has always been a cross-cultural curiosity. This perpetual Lunar Calendar has an abacus and a tide calculator. Its function is to predict the time of the tides and the intimate relationship of these with the influence of the rotation of the moon in its orbit around the Earth.
