Venus Mahadasha, Mars Antardasha (Shukra–Mangal)

The Mars antardasha is the fourth of the nine sub-periods inside the Venus mahadasha. 20 × 7 ÷ 120 makes the Venus–Mars 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.

Mars’s turn in the Venus mahadasha comes only after Venus, the Sun and the Moon have run, which takes 6 years. When the Venus–Mars sub-period gives way to Venus–Rahu, 12 years 10 months of the Venus mahadasha remains.

Mars’s 7 years make every Mars antardasha 7/120 of the mahadasha containing it, so inside Venus’s 20 years the Venus–Mars sub-period is the seventh-longest of the nine, level with Venus–Ketu, because Ketu and Mars each run 7 years as mahadashas.

The Nine Pratyantardashas of Venus–Mars

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

How Venus and Mars Stand to Each Other

On the natural friendship table, Venus and Mars each count the other neutral. The Venus–Marsrelationship is mutual, so it reads the same from either lord.

Counted between the signs they own, Aries is the 12th from Venus’s Taurus, Scorpio is the 7th from Venus’s Taurus, Aries is the 7th from Venus’s Libra and Scorpio is the 2nd from Venus’s Libra. Whatever the ascendant, the houses Venus rules and the houses Mars rules sit at those same distances from each other in the chart, so the Venus–Mars sub-period always joins lordships that far apart.

The Same Pair the Other Way Round: Mars–Venus

20 × 7 equals 7 × 20, so the Venus antardasha of the Mars mahadasha is exactly as long as Venus–Mars: 1 year 2 months. Nothing else about Mars–Venus matches. It is the seventh sub-period of Mars’s 7 years rather than the fourth of Venus’s 20; it opens after 4 years 10 months 24 days of the Mars mahadasha, against 6 years here; and its pratyantars start from Venus instead of Mars.

What the Texts Assign to Venus and Mars

The karaka list the tables give Venus, the mahadasha lord, is marriage, vehicles, art, music, luxury, hotels and cosmetics; for Mars, the lord of the Venus–Mars sub-period, it is younger siblings, land and property, weapons, engineering and the armed forces. Parashari practice reads the sub-period through the houses each of the two owns and occupies in the birth chart, and through where Mars stands counted from Venus there. None of that is a forecast, and this page makes none: without a chart, Venus–Mars 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 Bharani, Purva Phalguni or Purva Ashadha opens life inside the Venus mahadasha itself, part-way through, and whether the Venus–Mars sub-period is still ahead depends on how far the Moon had gone into the nakshatra. For a birth in Mrigashira, Chitra or Dhanishta, the Mars mahadasha comes first, and the Venus mahadasha is the seventh in that sequence.
