Rahu Mahadasha, Jupiter Antardasha (Rahu–Guru)

The Jupiter antardasha is the second of the nine sub-periods inside the Rahu mahadasha. 18 × 16 ÷ 120 makes the Rahu–Jupiter sub-period 2 years 4 months 24 days on the classical year of twelve thirty-day months, which is how the texts state it, or 877 days on the solar year of 365.2425 days that the dasha calculator uses.

Jupiter’s turn in the Rahu mahadasha comes only after Rahu has run, which takes 2 years 8 months 12 days. When the Rahu–Jupiter sub-period gives way to Rahu–Saturn, 12 years 10 months 24 days of the Rahu mahadasha remains.

Jupiter’s 16 years make every Jupiter antardasha 16/120 of the mahadasha containing it, so inside Rahu’s 18 years the Rahu–Jupiter sub-period is the fifth-longest of the nine.

The Nine Pratyantardashas of Rahu–Jupiter

A pratyantardasha of Rahu–Jupiter is 18 × 16 × its own lord’s years ÷ 14,400, and the nine run in cycle order starting from Jupiter. Venus’s is the longest inside Rahu–Jupiter at 144 days and the Sun’s the shortest at 43 days, on the classical year and rounded to the day.

How Rahu and Jupiter Stand to Each Other

Rahu’s row in the friendship lists counts Jupiter neutral. Jupiter’s row names no node, so the other direction of the Rahu–Jupiter relationship has no entry, and this page does not supply one. The nodes have no row in the seven-graha table that kundli matching uses; the node’s own entry is the one printed on its planet page.

Rahu owns no sign in the standard scheme, so the Rahu–Jupiter sub-period has no fixed distance between lordships. What stands in for it is the node’s dispositor — the lord of the sign Rahu occupies at birth — which differs from chart to chart.

The Same Pair the Other Way Round: Jupiter–Rahu

18 × 16 equals 16 × 18, so the Rahu antardasha of the Jupiter mahadasha is exactly as long as Rahu–Jupiter: 2 years 4 months 24 days. Nothing else about Jupiter–Rahu matches. It is the ninth sub-period of Jupiter’s 16 years rather than the second of Rahu’s 18; it opens after 13 years 7 months 6 days of the Jupiter mahadasha, against 2 years 8 months 12 days here; and its pratyantars start from Rahu instead of Jupiter.

What the Texts Assign to Rahu and Jupiter

The karaka list the tables give Rahu, the mahadasha lord, is foreign lands and foreigners, technology, aviation and politics; for Jupiter, the lord of the Rahu–Jupiter sub-period, it is children, teachers and gurus, higher learning and dharma. Parashari practice reads the sub-period through the houses each of the two owns and occupies in the birth chart (for Rahu, which owns none, the house it occupies and the lord of its sign), and through where Jupiter stands counted from Rahu there. None of that is a forecast, and this page makes none: without a chart, Rahu–Jupiter is a length and a position, and the 2 years 4 months 24 days above is the whole of what can be said about it in general.

A birth with the Moon in Ardra, Swati or Shatabhisha opens life inside the Rahu mahadasha itself, part-way through, and whether the Rahu–Jupiter sub-period is still ahead depends on how far the Moon had gone into the nakshatra. For a birth in Punarvasu, Vishakha or Purva Bhadrapada, the Jupiter mahadasha comes first, and the Rahu mahadasha is the ninth in that sequence.

The Other Sub-Periods of the Rahu Mahadasha

The full table for the Rahu mahadasha, with where each sub-period opens and closes, is on the Rahu mahadasha page. How the Rahu mahadasha is read as a whole is in our Rahu mahadasha article, and the system itself in Vimshottari dasha explained. This page in Hindi: राहु महादशा में गुरु अंतर्दशा.
