Summary
[edit]DescriptionPrecession of Equinoxes 2024 Map.pdf |
English: The Precession of the Equinoxes was first described by the Greek astronomer Hipparchus who lived between 190-120 BC. The precession of the equinoxes is a cycle where in the March Equinox moves very slowly through the Zodiac constellations of the Ecliptic and takes an estimated 26,000-years to come around full circle. The earliest record of this is the ancient Babylonian calendar which has the March 21 equinox, (the time point when Earth’s equator lines directly up with the Sun) in the constellation Aries. From there it would continue to line up in Aries until crossing the borderline into Pisces sometime around the year 319 B.C. From there it will continue to line up in Pisces where it is now until sometime around the year 2601 A.D. when the March Equinox will cross the borderline from Pisces into Aquarius. From there it would continue to line up in Aquarius until sometime around the Year 4,401 A.D. when the March equinox will cross over the borderline from Aquarius into Capricorn.
The Constellation border lines and dates of this calendar are all based on Universal time in the year 2024 and are calculated to the constellation boundaries standardized in 1930 by the International Astronomical Union. The March 20 Equinox lines up in Pisces. The June 20 Solstice lines up in Taurus the day before Tauru-Gemini cusp. The September 22 Equinox lines up in Virgo. The December 21 Solstice lines up in Sagittarius. |
