The Jupiter Mahadasha for Aquarius Ascendant
16 years · Jupiter rules the 2nd and 11th
The Parashari way to read a mahadasha for a given ascendant starts with the houses its lord holds. For Aquarius ascendant Jupiter rules the 2nd (Pisces) and the 11th (Sagittarius), so for Aquarius the 16-year Jupiter mahadasha carries both an unclassed house and an upachaya house.
Counted from Aquarius, Jupiter is exalted in the 6th (Cancer) and debilitated in the 12th (Capricorn). Saturn, Aquarius’s lagna lord, and Jupiter count each other neutral. Jupiter’s own nakshatras fall in Punarvasu (the 5th and 6th), Vishakha (the 9th and 10th) and Purva Bhadrapada (the 1st and 2nd) for Aquarius ascendant, which is where a birth that opens in the Jupiter mahadasha has its Moon.
The Nine Sub-Periods, by Lordship for Aquarius
| # | Antardasha | Length (classical) | Its lord rules, for Aquarius |
|---|---|---|---|
| 1 | Jupiter–Jupiter | 2 years 1 month 18 days | the 2nd and the 11th |
| 2 | Jupiter–Saturn | 2 years 6 months 12 days | the 1st and the 12th |
| 3 | Jupiter–Mercury | 2 years 3 months 6 days | the 5th and the 8th |
| 4 | Jupiter–Ketu | 11 months 6 days | no house |
| 5 | Jupiter–Venus | 2 years 8 months | the 4th and the 9th |
| 6 | Jupiter–Sun | 9 months 18 days | the 7th |
| 7 | Jupiter–Moon | 1 year 4 months | the 6th |
| 8 | Jupiter–Mars | 11 months 6 days | the 3rd and the 10th |
| 9 | Jupiter–Rahu | 2 years 4 months 24 days | no house |
For Aquarius ascendant, three of the Jupiter mahadasha’s sub-periods belong to lords of a dusthana (the 6th, 8th or 12th): Jupiter–Saturn, Jupiter–Mercury and Jupiter–Moon, and two to lords of a trikona other than the 1st: Jupiter–Mercury and Jupiter–Venus. The sub-period of Saturn, Aquarius’s lagna lord, is Jupiter–Saturn, the second of nine, 2 years 6 months 12 days long. Counted in time, sub-periods whose lords hold a dusthana for Aquarius take 6 years 1 month 18 days (38%) of the Jupiter mahadasha’s 16 years, and those whose lords hold a trikona other than the 1st take 4 years 11 months 6 days (31%); a lord holding both is counted in both. In the Jupiter mahadasha for Aquarius, the Rahu and Ketu sub-periods are read through their dispositors in the chart, since neither node rules a house.
For an Aquarius-rising chart this is the frame of the Jupiter mahadasha, not a forecast: where Jupiter and each sub-period lord actually sit, and their dignity there, decide what it comes to, and this page cannot know either.
