Instrument used to predict the time of the passage of the tides and the intimate relationship of these with the influence of the rotation of the Moon in its orbit around the Earth. The tide calculator, on the other hand, has the function of calculating the schedules of these, since with their constant change of water level, they have important effects for navigation, ports and fishing, for the energy generated by the immense quantity of water they move and their influence on underwater currents.

The moon in its displacement around the Earth, describes an orbit or synodic month of 29.53 days (equivalent to 360º / 29.53 or 12.19º daily) with respect to a given meridian, where it will always show the 12 solar hours. On Earth, the two stars that influence the gravitational attraction on the liquid masses (seas) are the Moon and the Sun. The infinity of the Moon is two and a half times higher than the Sun and not due to its mass, but to the distance that separates us from her.
