Budh Aditya Yoga Calculator

Mercury never travels more than twenty-eight degrees from the Sun. That is an orbital fact, not an astrological one, and it means the two are in the same sign in something close to half of all charts. Budha-Aditya Yoga — the conjunction read for intelligence, articulacy and success in study — is therefore one of the most common combinations in the entire system.

The complication is combustion. A planet too close to the Sun is astamgata, burnt, and is read as having lost its independent voice. Mercury within about fourteen degrees of the Sun is combust by the usual convention, and the same conjunction that forms Budha-Aditya frequently produces a combust Mercury. Two classical doctrines therefore point in opposite directions about the same placement, and the texts do not resolve it cleanly.

This calculator checks the house conjunction, which is what the engine detects: the Sun and Mercury in the same house. It does not compute combustion, and it does not claim to. Where a page reports the yoga present, the honest next question is the exact separation in degrees, which the birth chart on /kundli gives.

Saraswati Yoga

Mercury, Venus and Jupiter in angles or trines — at least two of the three in the engine's check. Named for the goddess of learning and read for intelligence, creativity and articulacy, and a considerably rarer combination than Budha-Aditya.

Bhadra Yoga

Mercury in its own sign or exalted, in an angle. One of the five Pancha Mahapurusha yogas and the Mercurial one, so it is the strongest statement about Mercury a chart can make.

Vesi, Vasi and Ubhayachari

Benefics in the 2nd from the Sun, in the 12th, and in both. The three solar yogas, read for eloquence, conduct and standing. They describe the Sun's neighbourhood in the same way Sunapha and Anapha describe the Moon's.

The combinations above were tested against a Gemini ascendant, and that single fact decides every one of them. A yoga defined by the second and eleventh lords is a statement about two specific planets, and which two depends entirely on which sign was rising. Change the ascendant and you change the lords, the categories they belong to, and therefore the answer.

The categories are the vocabulary the whole yoga literature is written in. Kendras — the 1st, 4th, 7th and 10th — are the pillars: the houses that hold a chart up. Trikonas — the 1st, 5th and 9th — are the sources of fortune and merit. A Raja Yoga is a link between a lord of one group and a lord of the other, and that is the whole definition. Dusthanas — the 6th, 8th and 12th — are the houses of difficulty, and a lord of a dusthana placed in another dusthana is the Viparita reversal. Upachayas — the 3rd, 6th, 10th and 11th — are the houses that improve with time, which is why malefics there are read differently from malefics anywhere else.

The first house belongs to two categories at once, being both a kendra and a trikona, and that is not a bookkeeping accident: it is why the ascendant lord is the single most important planet in a Parashari reading, and why a yoga involving it carries more weight than the same structure built from any other pair.

The occupants column is there because a house lord and a house occupant are different things and are constantly confused. A planet sitting in the tenth house is not the tenth lord unless it also rules the sign there. Most yoga definitions are about lords; a few — Budha-Aditya, Chandra-Mangal, the Mahapurusha set — are about occupants. The table gives you both so a definition can be checked rather than taken on trust.

1. Confirm the conjunction, then get the separation The house check is the yoga. The degrees between the Sun and Mercury decide whether Mercury is combust, and that is the difference between the two doctrines. The birth chart on /kundli prints both longitudes.
2. Check Mercury's dignity Mercury in Virgo is exalted, in Pisces debilitated. A Budha-Aditya formed by an exalted Mercury and one formed by a debilitated one are not the same placement, and no house check distinguishes them.
3. Read the house they share The conjunction in the tenth reads for public articulacy; in the fifth for study and creative intelligence; in the twelfth for work done privately. The house is where the combination operates.
4. Compare with Bhadra Yoga If Mercury also forms Bhadra — own sign or exalted, in an angle — the chart is making a much stronger statement about Mercury than Budha-Aditya alone. Bhadra is rare where Budha-Aditya is common.
5. Read the whole solar neighbourhood Vesi, Vasi and Ubhayachari describe what stands on either side of the Sun. Together with the conjunction they give a fuller picture of the solar situation than any one of them.

Every combination reported above is produced by a named detector in this site's astrology engine, not by a language model and not by a lookup table of pre-written paragraphs. A detector takes the planet-to-house map, the planet-to-sign map and the ascendant, applies one classical condition, and returns three things: whether the condition held, a strength between zero and one, and the rule it applied. All three are printed.

Strength is not a score. It reflects how firmly that detector's own condition was met — how many qualifying conjunctions were found, how many of the three benefics participated, how many debilitations were cancelled. It is calibrated per detector and is not a common currency, so adding the column up produces a number that means nothing. It exists so that a marginal case can be told from an emphatic one, and for no other purpose.

Absent combinations are printed. A calculator that lists only what it found leaves a reader unable to distinguish a chart with no yogas from a check that ran incompletely, and the omission always flatters. Every page here reports the number tested alongside the number found, and both numbers come from the same list.

What is not checked is named rather than hidden. This engine has no detector for Dharma-Karmadhipati yoga — the ninth and tenth lords in conjunction or mutual aspect — so no page here claims to test it. It has none for Kaal Sarp Dosha either. Both are well-known enough that their absence looks like an oversight, which is precisely why it is stated: a row that silently reports 'not present' for a condition nothing evaluated is a lie a reader cannot detect.

The Pancha Mahapurusha set is assembled in exactly one place in the engine. It used to be detected in two modules at once, so three of the five came back twice in a single chart and Saturn's came back under two different spellings — which inflated both the count of yogas a chart carried and the scores derived from it. The count this page reports is a real count.

Almost every combination on this page is defined by house position or by house rulership, and houses are the part of a chart that moves fastest. The ascendant travels through all twelve signs every twenty-four hours — roughly one sign every two hours, and roughly one degree every four minutes — so an hour's error in a recorded birth time routinely changes the rising sign. Change the rising sign and every house lord changes with it, which changes most of the table above.

The planets themselves are far steadier. The Moon changes sign about every two and a quarter days, the Sun about every month, and Jupiter and Saturn are fixed across a whole day. So a combination defined purely by two planets sharing a sign survives a rough birth time, and one defined by houses does not. Where a result on this page depends on a house, treat it as provisional unless your birth time is recorded to the minute.

Every reading here assumes a rectified birth time. The same caution applies with more force to the divisional charts a combination should be checked against: beyond the D9 they are highly birth-time sensitive, and the D60 changes ascendant about every two minutes.

The ascendant is not a property of the instant alone. It is the point of the ecliptic rising over a particular horizon, so it is a function of the moment and of the coordinate together, and the two trade off exactly: the sky turns one degree every four minutes, and one degree of longitude is four minutes of local time. Moving one degree of longitude — about 103 km east or west at Indian latitudes — moves the ascendant a degree, and 3096 km moves it a whole sign. A different rising sign means different house lords, and every combination on this page is a statement about house lords.

Latitude matters separately and less obviously. It does not shift the clock, it changes how fast each sign climbs — the ascensional difference — so two places on the same meridian and the same instant still rise different degrees, and the gap grows the further from the equator you are. This is why a chart cast for a state capital is not a rounding of a chart cast for a village two districts away; it is a different chart that happens to look plausible.

So enter the town you were actually born in. The place search above accepts any village, town or city a geocoder knows, not a shortlist of metros, and it prints the latitude, longitude and timezone it used above the result so you can check them against a map. Since one whole sign of the ascendant is the unit this page is built from, a birth place picked for convenience damages the result in the same way and by the same mechanism as a birth time rounded to the nearest quarter hour.

Budha-Aditya is not rare and it does not mark anybody out. Mercury is never more than twenty-eight degrees from the Sun, so the conjunction occurs in close to half of all charts.

The yoga is not a measure of intelligence. Nothing in a chart is, and reading one as if it were is a claim that has never been supported by anything.

This check does not test combustion, which points the opposite way about the same placement. A positive result here is a house conjunction and not a verdict on Mercury's condition.

Two limits apply to every page in this family and are worth stating in one place. Divisional charts beyond the D9 are highly birth-time sensitive, and every reading here assumes a rectified birth time. And nothing on this site is medical, legal or financial advice: a chart is a traditional interpretive framework, not a diagnosis, not a forecast, and never a reason to delay professional help.

A combination found in the birth chart is a first reading, not a finished one. The classical instruction is to test it against the divisional charts, and above all against the Navamsa: a yoga formed by planets that hold their dignity in the D9 is described very differently from one formed by planets that collapse there. That cross-check is the single most useful thing a reader can do with a positive result, and almost no calculator performs it.

The sixteen vargas are Parashara's Shodashavarga, and the weighting between them — Vimshopaka Bala — puts the D1, D9 and D60 highest. Every one of them is computed on this site from the classical start-sign rules rather than the cyclic shortcut that collapses the D12 and D60 into Aries. The Navamsa calculator is the one to run next after a budh aditya yoga check; the Shashtiamsa calculator is the final dignity test, and it needs a birth time good to the minute.

Timing is a separate system again. A natal combination is a standing feature of a chart with no dates in it; when it expresses is a Vimshottari Dasha question, read from the periods of the planets that form it. Any tool that produces a date from a natal yoga has generated a sentence rather than read a chart.
