Ketu Mahadasha, Moon Antardasha (Ketu–Chandra)

The Moon antardasha is the fourth of the nine sub-periods inside the Ketu mahadasha. 7 × 10 ÷ 120 makes the Ketu–Moon sub-period 7 months on the classical year of twelve thirty-day months, which is how the texts state it, or 213 days on the solar year of 365.2425 days that the dasha calculator uses.

The Moon’s turn in the Ketu mahadasha comes only after Ketu, Venus and the Sun have run, which takes 1 year 11 months 3 days. When the Ketu–Moon sub-period gives way to Ketu–Mars, 4 years 5 months 27 days of the Ketu mahadasha remains.

The Moon’s 10 years make every Moon antardasha 10/120 of the mahadasha containing it, so inside Ketu’s 7 years the Ketu–Moon sub-period is the sixth-longest of the nine.

The Nine Pratyantardashas of Ketu–Moon

A pratyantardasha of Ketu–Moon is 7 × 10 × its own lord’s years ÷ 14,400, and the nine run in cycle order starting from the Moon. Venus’s is the longest inside Ketu–Moon at 35 days and the Sun’s the shortest at 11 days, on the classical year and rounded to the day.

How Ketu and the Moon Stand to Each Other

Ketu’s row in the friendship lists counts the Moon an enemy. The Moon’s row names no node, so the other direction of the Ketu–Moon 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–Moon 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.

The Same Pair the Other Way Round: Moon–Ketu

7 × 10 equals 10 × 7, so the Ketu antardasha of the Moon mahadasha is exactly as long as Ketu–Moon: 7 months. Nothing else about Moon–Ketu matches. It is the seventh sub-period of the Moon’s 10 years rather than the fourth of Ketu’s 7; it opens after 7 years 3 months of the Moon mahadasha, against 1 year 11 months 3 days here; and its pratyantars start from Ketu instead of the Moon.

What the Texts Assign to Ketu and the Moon

The karaka list the tables give Ketu, the mahadasha lord, is moksha, past-life skill, renunciation, occult knowledge and flags and banners; for the Moon, the lord of the Ketu–Moon sub-period, it is mother, the mind (manas), water, milk, the public, comfort and the home. 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 the Moon stands counted from Ketu there. None of that is a forecast, and this page makes none: without a chart, Ketu–Moon is a length and a position, and the 7 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–Moon sub-period is still ahead depends on how far the Moon had gone into the nakshatra. For a birth in Rohini, Hasta or Shravana, the Moon mahadasha comes first, and the Ketu mahadasha is the seventh 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 चन्द्र अंतर्दशा.
