Moon Mahadasha, Jupiter Antardasha (Chandra–Guru)

The Jupiter antardasha is the fourth of the nine sub-periods inside the Moon mahadasha. 10 × 16 ÷ 120 makes the Moon–Jupiter sub-period 1 year 4 months on the classical year of twelve thirty-day months, which is how the texts state it, or 487 days on the solar year of 365.2425 days that the dasha calculator uses.

Jupiter’s turn in the Moon mahadasha comes only after the Moon, Mars and Rahu have run, which takes 2 years 11 months. When the Moon–Jupiter sub-period gives way to Moon–Saturn, 5 years 9 months of the Moon mahadasha remains.

Jupiter’s 16 years make every Jupiter antardasha 16/120 of the mahadasha containing it, so inside the Moon’s 10 years the Moon–Jupiter sub-period is the fifth-longest of the nine.

The Nine Pratyantardashas of Moon–Jupiter

A pratyantardasha of Moon–Jupiter is 10 × 16 × its own lord’s years ÷ 14,400, and the nine run in cycle order starting from Jupiter. Venus’s is the longest inside Moon–Jupiter at 80 days and the Sun’s the shortest at 24 days, on the classical year and rounded to the day.

How the Moon and Jupiter Stand to Each Other

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

Counted between the signs they own, Sagittarius is the 6th from the Moon’s Cancer and Pisces is the 9th from the Moon’s Cancer. Whatever the ascendant, the houses the Moon rules and the houses Jupiter rules sit at those same distances from each other in the chart, so the Moon–Jupiter sub-period always joins lordships that far apart.

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

The Same Pair the Other Way Round: Jupiter–Moon

10 × 16 equals 16 × 10, so the Moon antardasha of the Jupiter mahadasha is exactly as long as Moon–Jupiter: 1 year 4 months. Nothing else about Jupiter–Moon matches. It is the seventh sub-period of Jupiter’s 16 years rather than the fourth of the Moon’s 10; it opens after 11 years 4 months of the Jupiter mahadasha, against 2 years 11 months here; and its pratyantars start from the Moon instead of Jupiter.

What the Texts Assign to the Moon and Jupiter

The karaka list the tables give the Moon, the mahadasha lord, is mother, the mind (manas), water, milk, the public, comfort and the home; for Jupiter, the lord of the Moon–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, and through where Jupiter stands counted from the Moon there. None of that is a forecast, and this page makes none: without a chart, Moon–Jupiter is a length and a position, and the 1 year 4 months above is the whole of what can be said about it in general.

A birth with the Moon in Rohini, Hasta or Shravana opens life inside the Moon mahadasha itself, part-way through, and whether the Moon–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 Moon mahadasha is the seventh in that sequence.

The Other Sub-Periods of the Moon Mahadasha

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