Ketu mahadasha for Dhanu (Sagittarius) Moon sign

In the Vimshottari system a life moves through nine long periods, each ruled by one planet. The planet that rules the period sets the tone of those years: the areas of life that come forward, and the kind of effort that pays.

The Ketu mahadasha lasts 7 years in full. Most people meet it partway through, so the part they live through can be shorter.

Ketu stands for detachment, insight, research and spiritual search. Its period tends to loosen ties to what no longer fits and turn attention inward; outer gains matter less than understanding.

Ketu owns no sign of its own, so it rules no house counted from Sagittarius. In its period it works through the lord of the sign it occupies at birth and the planets it sits with, and those are found only in your own chart.

Ketu has no natural friendship of its own with Jupiter, the lord of Sagittarius. It takes on the colour of the planets it is joined with in your chart, so the same period can feel very different from one person to the next.

Which mahadasha you are in, and when it began, depends on the Moon's nakshatra at the moment you were born, so it is personal to you. Even within the Ketu mahadasha, where the planet sits in your own chart and the sub-periods inside it shape the years more than your Moon sign alone.
