Gochar: how planetary transits are read, and what they can tell you

Transits are read from the Moon first

The classical convention for gochar is to count from the janma rashi — the sign the Moon occupied at your birth — not from the ascendant. This is why Sade Sati is defined from the Moon, and why two people with the same Moon sign share it regardless of birth time.

The ascendant is then the second layer, and it is what makes a transit specific to you: the same Saturn crossing the same sign is in your 10th house and someone else's 4th, and those are different readings of one event in the sky.

Only three planets are slow enough to matter much

The Moon changes sign every two and a half days and Mercury and Venus every few weeks. Those movements are too quick to describe a period of life, which is why transit readings concentrate on the slow planets: Saturn at about two and a half years per sign, Jupiter at about one year, and the nodes at about eighteen months.

That is also why we sell three transit reports and not nine. A reading of Mercury's transit would be out of date before it was delivered.

Dasha is the frame, transit is the trigger

This is the single most useful idea in transit reading, and the one most often left out. The Vimshottari dasha running in your chart decides which themes are live in a given stretch of years. A transit decides when, inside that stretch, something moves.

The consequence is that the same transit does not do the same thing to two people, or even to the same person twice. A Jupiter transit over your 10th house during the mahadasha of a planet connected to your 10th is a different event from the same transit twenty years earlier under a different lord. Any reading that gives you a transit without the dasha underneath it has told you about the sky, not about you.

Common questions

Should transits be read from the Moon sign or the ascendant?

From the Moon sign first — that is the classical convention for gochar and what Sade Sati is defined from. The ascendant is read as a second layer, and it is what makes the reading specific to your chart.

Which transits actually matter?

The slow ones. Saturn, Jupiter and the nodes stay long enough in a sign to describe a period. The faster planets change too often to be read that way.

Is a transit stronger than a dasha?

They do different jobs. The dasha sets which themes are available over years; the transit decides the timing within that. A transit against an unrelated dasha usually passes with little to show.

Where do I get my own transit dates?

From a calculation against your own chart, not from an article — any date printed in a published page goes stale. Our free transit and Sade Sati calculators compute them live, and the transit reports give the house-by-house reading with date ranges.
