Current planetary transits over your natal chart with interpretation.
This page places today's nine grahas over a saved birth chart. For each it gives the sign, the degree within that sign, the nakshatra and pada, whether the motion is direct or retrograde, and the house counted from the natal Moon, which is the count the classical gochara reading uses.
Three views sit behind tabs. The first is the table of current transits, which can be filtered by sign and by motion. The second is the set of transit readings counted from the Moon, each with the house it falls in, the areas it touches and an advisory line. The third is a daily summary with an overall verdict and score, the day's strongest transits, and the state of the Jupiter and Saturn double transit.
The classical table lists, for each graha, the houses counted from the natal Moon in which its transit gives favourable results. This engine's table is Phaladeepika 26.2: the Sun in the 3rd, 6th and 10th; the Moon in the 1st, 3rd, 6th, 7th and 10th; Jupiter in the 2nd, 5th, 7th and 9th; Mars and Saturn in the 3rd and 6th; Mercury in the 2nd, 4th, 6th, 8th and 10th; Venus everywhere other than the 6th, 7th and 10th; and every planet in the 11th.
The attribution matters and was corrected in this codebase: the table is not from the Brihat Parashara Hora Shastra, which has no gochara chapter at all. Two independent witnesses agree with it, which is why it is the one used.
The Moon row of each graha's Bhinnashtakavarga is bit for bit the same set of houses, and Prashna Marga 22.35 states that identity outright: prepare the Ashtakavargas of all the planets, mark the favourable positions from the Moon in each, and those are called Gochara.
Phaladeepika 26.2 closes by saying that Rahu and Ketu are similar to the Sun, which would give them the 3rd, 6th, 10th and 11th. This engine ships the 3rd, 6th and 11th for both nodes, and that divergence is deliberate and disclosed rather than quietly applied.
The reason is structural rather than a headcount. Prashna Marga 22.51 gives the nodes as for Saturn, which is the 3rd, 6th and 11th, and Prashna Marga is also the source of the nodes' vedha pairs that this engine uses. Taking one text's vedha pairs while taking another's favourable houses would be a composite that neither text states. Brihat Samhita 104.4, the earliest of the witnesses, omits the nodes entirely and so casts no vote.
Chandrashtama is flagged when the transiting Moon is in the eighth sign from the natal Moon. Because the Moon covers a sign in roughly two and a quarter days, it is a short window that recurs every month rather than a rare event.
The double transit block is a set intersection. The houses Jupiter influences, by occupation and by its aspects, are intersected with the houses Saturn influences the same way; when the two sets overlap, the overlapping houses are listed with their significations. It appears only when it is actually active, instead of sitting on the page as a card that says nothing on most days.
The transits themselves are the same in the sky for everyone. The reading is not, because every house count on this page starts from your natal Moon, so two people born on the same day with the Moon in different signs read the same transit from different houses and get different results.
The chart is computed on the Lahiri ayanamsha with Whole Sign houses, the project defaults, to sub-arcsecond precision, and the page recomputes whenever the active chart changes. Because the count runs from the Moon rather than the ascendant, the reading is less sensitive to an uncertain birth minute than a lagna-based one: the Moon moves about thirteen degrees a day, where the ascendant moves a full circle.
