Jupiter Saturn Cycles

Every twenty years Saturn and Jupiter will have a conjunction, and every 60 years that conjunction will return to the same sign. This is the basic saṁvatsara cycle where each of the sixty years of Jupiter’s cycle receives its own name. These years can be used for the prediction of individual nature as well as for yearly agricultural and economic prediction.

This is the astronomically correct map of the last few Saturn-Jupiter conjunctions

Every twenty years (19.859), Saturn and Jupiter will have a conjunction at about 123 degrees apart (approximately ninth from the previous conjunction). Every 60 years (59.577) that conjunction will return to the same sign. If a conjunction happened in Aries, in twenty years, the next will happen in Sagittarius, then Leo in twenty more years, and then back to Aries after 60 years from the original Aries conjunction. In this way, the conjunctions will move in trines of the same element creating a triangle in the zodiac.

This image is the ideal theoretical movement which would be created if the orbits were perfect circles. Each same sign conjunction (every sixty years) is 8.93 degrees forward from the last conjunction.

This movement of triangles (śakti-parivartana) was called the “Rotation of the Trigon of Great Conjunctions” in the West. The cycle will stay in one elemental trine for about 200 years, then it will enter the next element. When this cycle changes elements it was thought to show great change in the world, especially when moving over gaṇḍāntas (water to fire signs).

800 years of astronomically correct sidereal conjunctions of Jupiter and Saturn. Notice how the elliptical orbit of the planets create on off-center geometry and variation between the distances of the conjunctions. Notice the gap of the ayanāṁśa (variation of the procession) between 1246 CE and 2040CE. Also, notice in Taurus (2) where there needs to be two more conjunctions to create a complete circle (even after the standard 40 conjunctions) because of the backward motion of the ayanāṁśa- I have put the missing conjunctions in light grey to show where the next few conjunctions would be located.

The cycle will move through the elements every 800 years (794.37 years or 40 conjunctions) returning to within .93° of the starting point if one uses a tropical calculation. This 1° discrepancy creates a larger cycle in which the exact degree returns in 288,000 years (800 X 360). In Satya Yuga there are 6 of these cycles, in Tretā Yuga there are 4.5, in Dvāpara there are 3, and in Kali Yuga there are 1.5 which gives a total of 15 of the grand 288,000 cycles in a Mahāyuga.

800 years of astronomically correct tropical conjunctions of Jupiter and Saturn (40 conjunctions X 20 years). Notice the gap of 1 degree between 1246 CE and 2040 CE which creates perfect geometry within the cycle of conjunctions. 

Each year of this sixty year cycle (bārhaspatya saṁvatsara) is given its own name and interpretation. The first twenty from Prabhava to Vyaya correlate to Brahmā, Sarvajit to Parabhava to Viṣṇu, and the last twenty to Śiva.
