1. Great Year

   The term Great Year has more than one major meaning. It is defined by scientific astronomy as "The period of one complete cycle of the equinoxes around the ecliptic, or about 25,800 years". Ptolemy reported that his teacher Hipparchus, by comparing the position of the vernal equinox against the fixed stars in his time and in earlier observations, discovered that it shifts westward approximately one degree every 72 years. Thus the time it would take the equinox to make a complete revolution through all the zodiac constellations and return to its original position would be approximately 25,920 years. In the heliocentric model, the precession can be pictured as the axis of the Earth's rotation making a slow revolution around the normal to the plane of the ecliptic. The position of the Earth's axis in the northern night sky currently almost aligns with the star Polaris, the North Star. But as the direction of the axis is changing, this is a passing coincidence which was not always so and will not be so again until a Great Year has passed. The Platonic Year, which is also called the Great Year, has a different more ancient and mystical meaning. Plato hypothesized that winding the orbital motions of the Sun, Moon and naked eye planets forward or back in time would arrive at a point where they are in the same positions as they are today. He called this time period the Great Year and suggested that such a unified return would take place about every 36,000 years. By extension, the term "Great Year" can be used for any concept of eternal return in the world's mythologies or philosophies. Historian Otto Neugebauer writes: The difficulty with the term "great year" lies in its ambiguity. Almost any period can be found sometime or somewhere honored with this name.

1. great year

   A Great Year, also known as a Platonic Year or an Equinoctial Cycle, is the period of time required for the equinox to make a complete cycle of the zodiac due to the precession of Earth's axis. It is approximately 25,800 years but varies due to tidal forces and other factors. The concept of a Great Year has been used in astrology and ancient cultures to signify a complete cycle of the constellations.

1. Great Year

   The term Great Year has a variety of related meanings. It is defined by NASA as "The period of one complete cycle of the equinoxes around the ecliptic, about 25,800 years […] also known as [a] Platonic Year." One complete cycle of the equinoxes here means one complete cycle of axial precession, however such precession was unknown to Plato, who defined the "perfect year" as the return of the celestial bodies and the diurnal rotation of the fixed stars to their original positions. Cicero followed Plato in defining the Great Year as a combination of solar, lunar and planetary cycles Nicholas Campion writes of "periods of History, analogous to the solar year, known as 'Great Years' " Plato's description of the perfect year is found in his dialogue Timaeus In De Natura Deorum, Cicero wrote By extension, the term "Great Year" can also be used for any concept of eternal return in the world's mythologies or philosophies. Otto Neugebauer wrote Macrobius in his commentary on Cicero's Somnium Scipiones states that 'the philosophers' reckon the Great Year as 15,000 years. Censorinus wrote that Aristarchus of Samos reckoned a Great Year of 2484 years: it has been argued that this is a miscopying of 2434, which represents 15 Exeligmos cycles.
