Ketu Mahadasha, Venus Antardasha (Ketu–Shukra)

The Venus antardasha is the second of the nine sub-periods inside the Ketu mahadasha. 7 × 20 ÷ 120 makes the Ketu–Venus sub-period 1 year 2 months on the classical year of twelve thirty-day months, which is how the texts state it, or 426 days on the solar year of 365.2425 days that the dasha calculator uses.

Venus’s turn in the Ketu mahadasha comes only after Ketu has run, which takes 4 months 27 days. When the Ketu–Venus sub-period gives way to Ketu–Sun, 5 years 5 months 3 days of the Ketu mahadasha remains.

Venus’s 20 years make every Venus antardasha 20/120 of the mahadasha containing it, so inside Ketu’s 7 years the Ketu–Venus sub-period is the longest of the nine.

The Nine Pratyantardashas of Ketu–Venus

A pratyantardasha of Ketu–Venus is 7 × 20 × its own lord’s years ÷ 14,400, and the nine run in cycle order starting from Venus. Venus’s is the longest inside Ketu–Venus at 70 days and the Sun’s the shortest at 21 days, on the classical year and rounded to the day.

How Ketu and Venus Stand to Each Other

Ketu’s row in the friendship lists counts Venus a friend. Venus’s row names no node, so the other direction of the Ketu–Venus 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.

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

Ketu is debilitated in Taurus, a sign Venus owns (on the commoner reckoning; planets.js gives another sign as well). In the Ketu–Venus sub-period, then, one lord's dignity is placed on the other’s ground.

The Same Pair the Other Way Round: Venus–Ketu

7 × 20 equals 20 × 7, so the Ketu antardasha of the Venus mahadasha is exactly as long as Ketu–Venus: 1 year 2 months. Nothing else about Venus–Ketu matches. It is the ninth sub-period of Venus’s 20 years rather than the second of Ketu’s 7; it opens after 18 years 10 months of the Venus mahadasha, against 4 months 27 days here; and its pratyantars start from Ketu instead of Venus.

What the Texts Assign to Ketu and Venus

The karaka list the tables give Ketu, the mahadasha lord, is moksha, past-life skill, renunciation, occult knowledge and flags and banners; for Venus, the lord of the Ketu–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 (for Ketu, which owns none, the house it occupies and the lord of its sign), and through where Venus stands counted from Ketu there. None of that is a forecast, and this page makes none: without a chart, Ketu–Venus is a length and a position, and the 1 year 2 months above is the whole of what can be said about it in general.

A birth with the Moon in Ashwini, Magha or Mula opens life inside the Ketu mahadasha itself, part-way through, and whether the Ketu–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 Ketu mahadasha is the ninth in that sequence.

The Other Sub-Periods of the Ketu Mahadasha

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