Jupiter Mahadasha, Venus Antardasha (Guru–Shukra)

The Venus antardasha is the fifth of the nine sub-periods inside the Jupiter mahadasha. 16 × 20 ÷ 120 makes the Jupiter–Venus sub-period 2 years 8 months on the classical year of twelve thirty-day months, which is how the texts state it, or 974 days on the solar year of 365.2425 days that the dasha calculator uses.

Venus’s turn in the Jupiter mahadasha comes only after Jupiter, Saturn, Mercury and Ketu have run, which takes 7 years 10 months 12 days. When the Jupiter–Venus sub-period gives way to Jupiter–Sun, 5 years 5 months 18 days of the Jupiter mahadasha remains.

Venus’s 20 years make every Venus antardasha 20/120 of the mahadasha containing it, so inside Jupiter’s 16 years the Jupiter–Venus sub-period is the longest of the nine.

The Nine Pratyantardashas of Jupiter–Venus

A pratyantardasha of Jupiter–Venus is 16 × 20 × its own lord’s years ÷ 14,400, and the nine run in cycle order starting from Venus. Venus’s is the longest inside Jupiter–Venus at 160 days and the Sun’s the shortest at 48 days, on the classical year and rounded to the day.

How Jupiter and Venus Stand to Each Other

On the natural friendship table, Jupiter counts Venus an enemy while Venus counts Jupiter neutral. The table is not symmetric, so the Jupiter–Venus relationship has to be quoted in both directions, as it is here, rather than as one word.

Counted between the signs they own, Taurus is the 6th from Jupiter’s Sagittarius, Libra is the 11th from Jupiter’s Sagittarius, Taurus is the 3rd from Jupiter’s Pisces and Libra is the 8th from Jupiter’s Pisces. Whatever the ascendant, the houses Jupiter rules and the houses Venus rules sit at those same distances from each other in the chart, so the Jupiter–Venus sub-period always joins lordships that far apart.

Venus is exalted in Pisces, a sign Jupiter owns. In the Jupiter–Venus sub-period, then, one lord's dignity is placed on the other’s ground.

The Same Pair the Other Way Round: Venus–Jupiter

16 × 20 equals 20 × 16, so the Jupiter antardasha of the Venus mahadasha is exactly as long as Jupiter–Venus: 2 years 8 months. Nothing else about Venus–Jupiter matches. It is the sixth sub-period of Venus’s 20 years rather than the fifth of Jupiter’s 16; it opens after 10 years 2 months of the Venus mahadasha, against 7 years 10 months 12 days here; and its pratyantars start from Jupiter instead of Venus.

What the Texts Assign to Jupiter and Venus

The karaka list the tables give Jupiter, the mahadasha lord, is children, teachers and gurus, higher learning and dharma; for Venus, the lord of the Jupiter–Venus sub-period, it is marriage, vehicles, art, music, luxury, hotels and cosmetics. Parashari practice reads the sub-period through the houses each of the two owns and occupies in the birth chart, and through where Venus stands counted from Jupiter there. None of that is a forecast, and this page makes none: without a chart, Jupiter–Venus is a length and a position, and the 2 years 8 months above is the whole of what can be said about it in general.

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