About the Jupiter transit
What is a Jupiter transit?
A Jupiter transit is Jupiter moving out of one sign of the zodiac and into the next. Jupiter takes close to twelve years to complete one circuit of the Sun, which works out to roughly a year in each sign, so this is a change that comes round about once a year — and that annual turnover is why it gets read as setting the tone of a year. Saturn, by contrast, takes about two and a half years per sign.
The same event has several names depending on which tradition you grew up with. In Hindi almanacs it is guru gochar or guru rashi parivartan; in Tamil it is guru peyarchi; you will also see jupiter gochar and guru transit used interchangeably. All of them describe what this page shows: Jupiter changing rashi. The Tamil version of this page, with the same computed dates, is at குரு பெயர்ச்சி.
Read from your Moon sign, not your Sun sign
This is the step most people get wrong, and getting it wrong still produces a plausible-looking answer. Vedic gochara counts a transit from the rashi — the sign the Moon occupied at the moment you were born — not from the Sun sign a newspaper column uses. The two are usually different signs, so reading a Jupiter transit against your Sun sign gives you the table row belonging to someone else.
Once you know your Moon sign, the count is simple. Start at your Moon sign as house one and count forward to the sign Jupiter is in. With Jupiter in Cancer, every one of the twelve possible answers is in the table above, so there is nothing to work out by hand. And because the same transit lands on a different house for every rashi, it is favourable and unfavourable at the same time, for different people — there is no such thing as a Jupiter transit that is simply good.
Which houses Jupiter is favourable in
The classical gochara tables are specific about this. Counted from the Moon, Jupiter transiting the 2nd, 5th, 7th, 9th and 11th houses is treated as favourable. The 6th, 8th and 12th are the dusthana houses, read as the difficult ones. The 3rd, 4th and 10th are neither — and saying so is more honest than sorting all twelve signs into good and bad, which is what most yearly round-ups do. This page uses exactly the same rule as the 2027 horoscope pages, so the two can never disagree about the same placement.
Jupiter transit in the 8th house
The 8th from the Moon is one of the three dusthana positions, and it is the one people search for most. The classical reading is unfavourable, and the traditional advice attached to it is about restraint rather than disaster: do not extend yourself on credit, do not treat an optimistic forecast as a settled fact, and expect effort to convert into results more slowly than the same effort did a year earlier. Worth keeping in proportion, though — Jupiter is in the 8th from exactly one rashi at a time, and simultaneously in the 2nd from another, so the transit itself is not carrying any misfortune around with it.
Jupiter transit in the 12th house
The 12th is the second dusthana position, and it is the one immediately before Jupiter reaches your own Moon sign — so for whichever rashi has it, the following year brings Jupiter onto the Moon itself. The classical reading is of outgoings exceeding what you planned for and of energy going into things that do not obviously return anything. The 6th house, the third of the three, is read along similar lines.
Jupiter transit in the 7th house, and the other favourable ones
The 7th is one of the five favourable positions and the one most often looked up of those, because the 7th house is the one traditionally read for marriage and partnership. The other four: the 2nd is read for resources and family, the 5th for children, learning and anything creative, the 9th for fortune and travel, and the 11th is the position the texts are most positive about, read for gains and for the people around you. The yearly pages carry the full reading for each of these rather than the one-line version.
Jupiter on your own Moon sign
Jupiter transiting the sign your Moon is in — the 1st house — is not the easy year people expect from it, and the table above calls it mixed rather than favourable for that reason. The classical objection is specific: opportunities and offers multiply, spending loosens along with them, and the judgement that normally keeps you out of trouble turns optimistic at precisely the wrong moment. The usual reading is a busy year without a great deal to show for it.
A favourable house is not the end of the calculation
Classical gochara adds two corrections that most transit pages leave out. Vedha means obstruction: a planet sitting in a favourable house from your Moon can be blocked by another planet standing in one specific other house, and for as long as it stands there the good result is held back. Murti is the form a planet takes for the whole of a sign transit, read from where the Moon stood at the exact moment the planet changed sign, counted from your own Moon sign — so a single ingress hands a different form to each of the twelve rashis. That is the mechanism behind two people sitting under the same transit and getting visibly different years out of it. Both corrections are applied per sign on the 2027 horoscope pages.
Why other sites give a different Jupiter transit date
Two reasons, and both are legitimate. The first is retrograde motion. A planet near a sign boundary can cross it, reverse, cross back, and cross again months later, so one transit honestly has several dates; a site printing a single date has usually kept the first crossing and dropped the rest. Every crossing is listed above.
The second is the ayanamsha — the offset between the sidereal zodiac and the tropical one. This page uses Lahiri, the value most Indian almanacs follow, but Raman, Krishnamurti and others are all in use and they disagree by enough to move an ingress by a few days. Neither almanac is wrong; they are answering from a different zero point. Dates here are recomputed from Swiss Ephemeris positions, so they also do not drift the way a hand-typed table does.
Does this page predict anything?
No, and it is worth being plain about that. What is here is the part that can actually be computed: which sign Jupiter is in, when it changes, which house that is counted from your Moon sign, and what the classical tables say about that house. Everyone born with the Moon in the same sign shares every word of it. How a transit plays out for you specifically depends on your whole chart — which houses Jupiter rules for you, which dasha period you are running, what else aspects that house — and none of that can be read off an ingress date. For that, see a qualified astrologer.
Saturn is the other transit that decides a year
Jupiter and Saturn are the two slow-moving planets, and between them they carry most of what a yearly reading is based on. Saturn spends about two and a half years per sign, and the seven-and-a-half year stretch when it passes over your Moon sign and the signs either side of it is what sade sati means. The Tamil page for Saturn's sign change is at சனி பெயர்ச்சி, and the live positions of all nine grahas are on the transit wheel.
