The sky keeps moving after you are born
A birth chart freezes the planets at one moment. The planets themselves keep travelling, and their ongoing movement through the zodiac is called gochara, transit. Vedic astrology uses transits as the trigger in its timing system: the dasha says which chapter of life is open, and transits say when a page in that chapter turns. This guide explains how the classical texts read transits, why the same transit lands differently for different people, and how to tell an important one from background noise. For where every planet is today, see the live gochar page.
Speed decides importance
Not all transits are equal, and one of the main reasons is speed. A planet that crosses a sign in two days cannot shape a year. Approximate times per sign:
- Moon: about two and a quarter days. It sets the mood of a day and is the backbone of the panchang.
- Sun: about a month. The Sun's entry into each sign is a sankranti, and Makar Sankranti is the best known.
- Mercury and Venus: roughly three to five weeks, longer when retrograde.
- Mars: about six weeks, but it can stay several months in one sign around its retrograde.
- Jupiter: about a year, completing the zodiac in roughly twelve.
- Rahu and Ketu: about eighteen months, almost always moving backwards and always opposite each other.
- Saturn: about two and a half years, completing the zodiac in roughly twenty-nine and a half.
Saturn, Jupiter and the nodes are the transits that line up with life chapters: a move, a career shift, a marriage, a loss. The fast planets mostly colour days and weeks. That is also why Mercury retrograde deserves far less dread than it gets.
Transits are counted from the Moon
Here Vedic practice parts company with most Western transit reading. The classical gochara rules count a transiting planet's position from the natal Moon sign, not from the ascendant and not from the Sun. If your Moon is in Cancer and Saturn moves into Pisces, Saturn is transiting your ninth from the Moon, whatever your lagna or your newspaper sign. Knowing your Moon sign is therefore the first requirement. The Moon sign calculator finds it from your birth details.
The texts then list, for each planet, the houses from the Moon where its transit is favourable. The commonly cited scheme is:
- Sun: 3rd, 6th, 10th and 11th
- Moon: 1st, 3rd, 6th, 7th, 10th and 11th
- Mars and Saturn: 3rd, 6th and 11th
- Rahu and Ketu: 3rd, 6th, 10th and 11th
- Mercury: 2nd, 4th, 6th, 8th, 10th and 11th
- Jupiter: 2nd, 5th, 7th, 9th and 11th
- Venus: every house except the 6th, 7th and 10th
The pattern is easy to see. The malefics do well in the upachaya houses (3, 6, 10, 11), houses of effort and gain: Mars and Saturn in three of the four, the 3rd, 6th and 11th, and the nodes in all four, where their friction becomes drive. Venus does well almost everywhere; Jupiter only in five houses, Mercury in six.
Vedha: when a good transit is blocked
The tradition adds a refinement called vedha, obstruction. Each favourable transit position has a paired point, and if another planet is transiting that point at the same time, the good result is said to be obstructed. Jupiter's favourable 11th, for instance, is obstructed by a planet in the 8th from the Moon, and its favourable 5th by one in the 4th. The rule has its own exceptions: the Sun and Saturn do not obstruct each other, and neither do the Moon and Mercury. Vedha is one reason two people with "the same" transit report different years.
The transits people ask about
Sade Sati
When Saturn transits the twelfth, first and second signs from the natal Moon, about seven and a half years in all, the period is called Sade Sati. It is the most feared transit in popular astrology and the most misunderstood. The texts associate it with pressure, responsibility, restructuring and the testing of whatever was built carelessly. They do not associate it with uniform disaster. Its weight varies with Saturn's role in the chart, the strength of the Moon and the dasha running at the time.

Saturn in the fourth and the eighth
Two other Saturn transits from the Moon have names. In the fourth it is ardhashtama ("half-eighth"), associated with domestic strain and a sense of being unsettled. In the eighth it is ashtama Shani, associated with obstacles and fatigue. Both are read with the same caveats as Sade Sati.
Jupiter's year in each sign
Jupiter's transit through the favourable houses from the Moon (2nd, 5th, 7th, 9th, 11th) is classically linked to growth in those houses' themes: savings and family in the 2nd, children and study in the 5th, partnership in the 7th, teachers and fortune in the 9th, gains in the 11th. Its return to the natal Moon sign every twelve years or so is classically counted unfavourable, associated with displacement and expense, since the first house is not in its favourable list.
The nodal axis
Rahu and Ketu shift sign together about every eighteen months, so the axis they occupy activates a pair of opposite houses: self and partner, home and career, and so on. Their transits over the natal Sun or Moon, and the eclipses that fall near those points, are watched closely in the tradition.
Two refinements that sharpen transit reading
Ashtakavarga scores
Parashara's ashtakavarga system gives each sign a score from each planet's point of view, between 0 and 8 points (bindus). A slow planet transiting a sign where it has many bindus is read as giving better results than the same planet in a sign where it has few. Four of eight is the usual threshold. The combined table, the sarvashtakavarga, totals 337 points across the twelve signs, an average of about 28. Signs well above that average are read as "strong rooms" for any transit. This is one of the main reasons two people with the same Moon sign can have very different experiences of the same Saturn transit.
Transit plus dasha
The most important rule is the simplest: a transit can only deliver what the chart and the running dasha already promise. Jupiter crossing your seventh from the Moon is unlikely to coincide with a marriage in a period that has nothing to do with partnership. During the dasha of your seventh lord, or of Venus, the same transit is far more likely to coincide with one. Many practitioners also watch for the moment when Jupiter and Saturn both influence the same house, by transit or aspect, and treat that as the point where a promised event becomes ripe. Our piece on what living through a dasha change is like and the Vimshottari dasha reference cover the timing half of this pairing.
Reading a transit, step by step
- Locate it from the Moon. Count the transiting planet's sign from your Moon sign and check it against the favourable houses above.
- Check for vedha. Is another planet sitting on the obstruction point?
- Look it up in ashtakavarga. How many bindus does the planet have in the sign it is crossing?
- Ask what it rules for you. Saturn as your ninth and tenth lord is a different visitor from Saturn as your eighth lord.
- Hold it against the dasha. Does the running period have anything to say about the houses involved?
Five checks sound like a lot, but each takes a minute once you have the chart in front of you, and together they turn a frightening headline ("Saturn enters your sign!") into a sober reading of what is actually likely to be emphasised.
What transits cannot do
A transit is weather, not climate. It can accelerate, delay or colour what the birth chart and the dasha have set up. It cannot by itself create an event the chart doesn't support, and no transit, Sade Sati included, is a verdict on anyone's life. Used that way, gochara is one of the most practical tools in Jyotish: it tells you which months to push, which to consolidate and which to treat with extra care.
